114 Year old Steam Waggon, Restored to its Pristine Elegance.

114 Year old Steam Waggon, Restored to its Pristine Elegance.

All of our esteemed visitors, who have visited the Nehru Science Centre, Mumbai will recollect seeing the 114 year old Steam Waggon / Lorry, artefact, which is displayed in the science park of the centre. Unfortunately, you may have noticed that this Steam Waggon was not in good condition due to its ageing and wear and tear because of the sultry and humid climatic conditions in Mumbai. We had received feedback from many of our visitors asking us to try and restore our precious artefacts. Fortunately the Covid 19 challenge, which has compelled all museums including our science museum to be closed for visitors, has given us an opportunity to take up restoration of our precious locomotive collections during this lockdown period. I am extremely happy to present the outcome of our restoration of the Steam Lorry. We have also completed the restoration of another artefact the Horse Drawn Carriage and we will be taking up restoration of other locomotive artefacts one at a time and hope to complete the restoration of all the outdoor artefacts by March 2021. I would appeal to all our esteemed visitors to please visit the science centre as soon as the lockdown is lifted for seeing this newly restored Steam Lorry, which was gifted to our centre by Mazagaon Dock Ltd and commissioned at our park on 10th January 1980.

The open air Science Park of the Nehru Science Centre, Mumbai, was a trendsetter for the science museum movement in India. The first two Government science museums in the country, which preceded the Nehru Science Centre (NSCM in India, were the Birla Science and Technology Museum in Kolkata and the Visvesvaraya Industrial Technology Museum in Bangalore, both of which did not have an open air Science Park, which is one of the major attraction of the NSCM. Incidentally the science park in Mumbai spread across six acres of land, was inaugurated on 22nd December 1979, six years before the NSCM was formally dedicated to the nation - on 10th November 1985 - by the then Prime Minister of India, Shri Rajiv Gandhi. The science park of NSCM is the first such science park in India and  most likely it is also the world’s first science park, which has inspired other science centres in US to adopt this unique concept. Incidentally the UNESCO recognised this new concept as an unique informal science learning ambience. The science park has several hands on outdoor science exhibits demonstrating different principles of science and adding to the attraction of the science park are the vintage locomotive vehicles (precious artefacts) of yesteryears - the Railway locomotive engines (steam and electric) Horse drawn Car carriage, Tramcar, HAL HF 24 Marut Fighter aircraft and the Steam Waggon. These precious historic artefacts were acquired by the centre from different sources in India and the Steam Waggon, the topic of my blogpost today, was purchased by the Mazagaon Dockyard Ltd (MDL) for transportation of goods from the Sentinel Company, UK in 1906 which after serving for more than half decade was donated by MDL to NSCM in 1980. Incidentally the MDL donated two such Steam Waggon  to NSCM,  which arrived at the science park on 10th January 1980 and one of the Waggon which then transferred to our sister unit VITM, Bangalore.

It has been more than four decades since one the Steam Waggon donated by MDL to NSCM was commissioned for public display in the open air science park in NSCM, yet it continues to attract visitors, who routinely are seen posing for a photograph in front of the steam lorry (Waggon). Not just the steam lorry even the other locomotive artefacts have fascinated and are continuing to attract visitors, particularly young children who visit the NSCM in large numbers. Most unfortunately these outdoor artefacts, notwithstanding the best efforts taken by NSCM to avoid corrosion and damage due to unwelcome environmental conditions of humidity in Mumbai, have been damaged and over the years the damage has been quite severe. NSCM is among the very few museums in the country, which remains open to the public all days of the year, except on two days - Holi has Deepavali. Visitors to our museum, despite our best efforts to keep them away from physically touching the precious artefacts, have engaged themselves in touching these precious artefacts. Unlike the art and archeology museums, the science museums in India have been designed with an objective of engaging the visitors with hands on models and exhibits, which they can touch, interact and play and learn science in an informal non coercive ambience. Unfortunately or fortunately this welcoming and non coercive approach of NSCM, though has helped countless children and adults to learn and be attracted to science, has been counterproductive when it comes to preserving our artefacts In the science park.  Visitors in large numbers actively engage themselves with science park exhibits like swing ( scientific swings with with different time periods) etc. and this engagement unfortunately stretches on to the locomotive artefacts as well. But then since majority of the visitors to NSCM are children the science centre has never been strict and coercive when it comes to enforcing the discipline of not to touch the precious locomotive artefacts. Therefore, over a span of four plus decades the climatic conditions of Mumbai and visitors handling of the artefacts has led to substantial damage and wear and tear on the artefacts. 

The Covid 19 pandemic, which is plaguing the world with India counting for 9 lac plus confirmed Covid cases ( fortunately we are doing very well with recovery rate in excess of 60% and fatality less than 3%) has disrupted the global society and this disruption has badly hit museums across the world. In the four plus decades history of NSCM, it is for the first time that our museum has remained closed to the public for more than four long months.  Fortunately, even during this lockdown period we have been able to establish an extraordinary online connect with our audience through a plethora of well conceived and curated programmes, activities and content. For example the live annular eclipse program that we live streamed on our social media has been seen by more than three hundred thousand plus audience from across the world. Similarly most of our other online activities have been receiving an extraordinary response. The Covid challenge has also provided us an opportunity, notwithstanding the financial crisis that we are facing, to try and restore some of our precious artefacts during this lockdown period. During this period we have already completed the restoration of the Horse Drawn Carriage and also the Steam Lorry(Waggon). We have taken up the restoration of the electric locomotive which we hope to complete in the next couple of months and we re also aiming to restoring other locomotive artefacts as well, which we hope to complete during this financial year.

The historically significant Steam lorry also called the Steam Waggon ( note the spelling of Waggon not wagon) artefact, was purchased by MDL from England in 1906 and was used by MDL until the late 1950s when it became obsolete, In the early 1970s the work for the development of the Science Centre in Mumbai commenced and the first phase of the project was the opening of a Science Park on 22nd December 1979. By then the officials of NSCM had managed to convince the authorities of MDL to donate two of these precious Steam Lorries to NSCM, one of which was to be sent to Visvesvaraya Museum Bangalore. Immediately after the opening of the Science Park two of the Steam Lorries were collected from MDL and were brought to the Science Park campus in worli on 10th January 1980. One of the Steam Lorries great in colour was commissioned at Science park in Mumbai and the second one was transported to Bangalore Museum and this has been commissioned inside the Engines Hall in the main building in Visvesvaraya Museum, Bangalore. MDL, which donated these artefacts to us, is the oldest ship building company in India. The history of the MDL company and the shipbuilding yard, dates back to 1774, when a small dry dock was constructed in Mazagon by the two Williams - William Mackinnon and William Mackenzie, founders of the British India Steam Navigation Company. In the year 1906 two Steam Lorries were purchased by this company from Sentinel from UK, for transport of goods to the dockyard and back. 

In 1914, the Peninsular and Oriental Steam Navigation Company took over the ship operations at the dock from the British India Steam Navigation Company. This company was later registered as a public company in 1934. By then the steam lorries which were purchased earlier were in active use for transporting ship building materials. One of this Steam Lorries also called as Steam Waggon is now on display at the science park in our campus in NSCM. In the modern world of fast paced transportation that is primarily propelled by combustion engines, gas turbines and nuclear reactors, the steam engine transports may seem like a dinosaur relic of the past. But then without this game-changing historic invention of the steam engines, the modern world of transportation would never have advanced to this stage and perhaps the world of transportation may not have reached the current stage where the next generation Elon Musk envisaged Hyper-loop public transport now appears to be a reality sooner than later. Arguably we are now headed towards what is called the ‘Fourth Industrial Revolution’, which is destined to be governed by intelligent machines that have been engineered to think using quintessential Artificial Intelligence, which will drive future public transports like the Hyper-loop. A look back in history reveals that the prime mover for the shaping of the Industrial Revolution ( also dubbed as technology revolution) was the invention of the Steam Engine, which was the most important development of the Industrial Revolution that facilitated major advancements in the fields of mining, manufacturing, agriculture and most importantly transportation. The invention of the steam engine, which primarily moved the Steam lorry, not only shaped the Industrial Revolution but it also helped in bringing about rapid social and technological change that has shaped today’s world. Industrial Revolution was a period of great innovation and many of the machines and tools that we see today have been shaped by the inventions which happened during the Industrial Revolution. 

The invention of the steam engine would eventually lead to the revolution in road, sea and rail transportation around the globe. Steam Locomotive transportation allowed large-scale movement of resources and people over long distances. Previously the industry relied on man -and animal-powered wagons and carts for transportation and the ushering of the steam engine changed this forever and brought world a lot closer. The use of steam locomotives became quite common all over Europe. The steam engines were also most commonly used in other jobs like mining and agriculture. The genesis for the invention of the steam engine may go to  several prominent figures of the 18th and 19th centuries, who are credited with developing and improving the steam engine, however it was primarily the work of  British (Scottish) engineer James Watt, who deserves major credit for the invention of his wonder machine -  the Steam Engine -, which heralded new muscle power to the machines paving the way for the first Industrial Revolution. 

When James Watt (1736-1819) invented and created the first reliable steam engine in 1775, his invention would literally change the world. Watson’s invention of the steam engine relegated the older, less efficient models, like the Newcomen Engine to history and most of these machines were replaced by the more efficient Watson Steam Engine.  James Watson’s innovation, of adding a separate condenser, significantly improved steam engine efficiency, especially latent heat losses. Increased efficiency helped Watson’s new engine to instantly become very popular and ended up replacing all old Newcomen Engines that were installed in mines and factories across the world. The Watson’s Steam Engine served as one of the greatest inventions of the Industrial Revolution. Watson integrated a crankshaft and gears in his steam engine design, which became the prototype for all modern steam engines. The efficacy of the steam engine was so profound that it eventually led to incredible improvements in almost all industries, primarily the textile industry, across the world. Steam engines would also lead to the development of transport locomotives, which gained massive leap forward particularly in ship propulsion. 

The massive success of the steam engine in mining industry paved way for its utility in the transportation and this eventually shaped a revolution in transportation around the globe. Locomotives allowed large-scale movement of resources and people over long distances. Previously the industry relied on man -and animal-powered wagons and carts for transportation of men and materials. While several prominent figures of the 18th and 19th centuries are credited with developing and improving the steam engine, it was primarily the work of James Watt, who is credited with the invention of the Steam Engine -, which heralded new muscle power. Although the credit for the invention of the Steam Engine goes deservingly to James Watt, however, the history of steam-powered machines goes back to the early first century AD, almost 1800 years before the dawn of the Industrial Revolution. 

Greek inventor named Heron of Alexandria is credited with the design of the world's first aeolipile, or primitive steam turbine during the first century AD. Heron's aeolipile was designed to harvest the power of the steam and demonstrate it in rotating a sphere. Heron envisaged that steam power could be used as a means of propulsion. His experimental system consisted of a hollow sphere, mounted on a pair of tubes. When heated from below by fire, the tubes ‘transported’ steam to the sphere, where it was released through another series of tubes projecting from the sphere's centre. This movement of steam through the device caused the sphere to revolve, thus demonstrating the potential of the steam as a means of propulsion. Heron’s aeolipile can therefore be described as the first known device to transform steam into rotary motion. But it wasn't until the 17th century that attempts were made to harness the power exhibited by Heron's aeolipile for practical applications.

Although the basic concept for harnessing the power of the steam was envisaged much earlier but no substantial progress made until late seventeenth century. Newcomen, an ironmonger at Dartmouth realised that the high cost of using the power of horses to pump out water from the mines can be reduced by introducing a machine, which could do the task of the horse. With his assistant John Calley, a plumber, Newcomen experimented for more than 10 years on a steam pump. The outcome was an engine, which was superior to the  Johan Savery, Pump that were in vogue. Unfortunately since Savery had obtained a broad patent for his pump in 1698, Newcomen could not patent his engine. He therefore joined hands with Savery and entered into a partnership for producing Newcomen engine, the first of which was commissioned in 1712. Newcomen Engine was used extensively in pumping out water from the coal mines, which was earlier carried out by horse. However the arrival of Watson’s Steam Engine in 1776 soon pushed the Newcomen Engine to history and Watson’s steam engine proved to be a very efficient machine, which while improving the efficiency also brought down the cost.

Watson steam engine helped Britain lead the Industrial Revolution, which was impacting the world and the steam engine helped in the development of agricultural machineries, which arrived on British farms in the 1790s. This was followed later by portable and traction engines as well as cable-operated cultivation equipment’s all of which used steam engines. Steam offered the first opportunity to significantly increase farming productivity by replacing horses with engine power, and steam engine sales reached a peak in the 1890s. The supreme efficiency of the steam engine and its reputation for speed helped it to spread its reach beyond agriculture and mining circles, into other areas of the industry from metalworking to textiles and steam engine locomotives for transport. Watson was savvy businessman and pitched and marketed his invention by highlighting the number of horses his engine would replace and in the process a new term was coined for the measurement of power "horsepower" HP for short. The steam engines utility exponentially spread its net onto the transportation. 

One of the first companies to start harvesting the power of Watson’s steam engine in transportation was Alley & MacLellan, which was founded in 1875 in Glasgow by Irishman, Stephen Alley and his Scottish partner John Alexander MacLellan. This company was initially manufacturing valves and compressors for steam engines. Later they diversified into manufacturing steamships. Alley & MacLellan acquired Simpson and Bibby of Horsehay, manufacturer of steam powered road vehicles, in 1903. They then began producing steam road vehicles in 1905 and in 1906 introduced a 5 ton vertical-boiler wagon, which featured a 2-cylinder under type engine and chain drive. The MDL was among the first companies to purchase steam Lorries from Alley and MacLellan company in the very first year of its production - 1906. The demand for the steam wagons started raising exponentially and by 1915 the demand was so high that Alley & McLellan was forced to establish a separate works at Shrewsbury with the name of Sentinel Wagon Works Limited, which was solely dedicated for wagon production. Sentinel Waggon Works Ltd steam wagons were so successful that they remained in production with relatively few updates until the launch of Sentinel's famous Super in 1923. During this period the company was also producing steam railway locomotives and railcars, for railway companies and industrial customers.  Sentinel, along with another company Foden, dominated the steam road transportation market for nearly three decades. M/S Alley and Mclellan continued to be known for their high quality marine steam engines. 

The Steam Lorry or the Steam Waggon, which is displayed in the science park of the NSCM was purchased  from Alley and MacLellan by British India Steam Navigation Company, in the year 1906 and this company later became the Mazagaon Dock Shipbuilders Ltd. This Steam Lorry / Waggon was extensively used mainly to haul ships into the dry-dock and for transportation of materials. This Steam Lorry continued to remain in running condition till 1971, when it participated in a vintage car rally in Bombay. Steam used to be generated at 230 PSI by a vertical water tube coal fired boiler, which passed through a super heater to produce superheated steam at 150 degree Centigrade. Total heating surface in the boiler of the steam lorry was 36.5 Square feet and the grate area is 2.6 sq ft. Load carrying capacity of the wagon is 4 tons and maximum speed of Lorry was around 20 Kilometres per hour (12 Miles per hour). 

Accompanying photographs to this post show the condition of the steam lorry at different times even since it was gifted to the NSCM by MDL in 1980. In a span of four decades during which it was on display at our Centre, the Steam Lorry had deteriorated over time and this can be seen in the images. However during the lockdown period we have managed to restore this precious artefact and it now looks fairly new and has that majestic appeal. I earnestly hope that the lockdown to our Centre is lifted soon and we open our doors to our esteemed audience who will be in a position to see this newly restored precious artefact which is 114 years old.
