Oil-fired steam loco for hill railway

Equipped with new oil–fired system, the narrow gauge steam locomotive is all set to chug in the lush green Matheran Hill Railway in Maharashtra. The 96-year-old steam loco ‘B 794’ will henceforth run using high speed diesel as fuel instead of coal in the 20-km eco-sensitive section from Neral to Matheran located on the Western Ghats range in Raigad district.

The ‘B’ class engine was dispatched on Monday from the over 80-year-old Golden Rock Railway Workshop here, which was entrusted with the task of converting the firing system of the loco from coal to oil. The Golden Rock Workshop accomplished the firing system conversion work within a span of 30 days after receiving the loco in April end.

As coal-fired system was posing problems to environment besides causing fire at times from the small particles of burnt coal flying out of the loco’s chimney in the eco-sensitive Matheran region, the Railways decided to convert the loco into oil-fired to avoid such situations in future, workshop officials said. The Golden Rock Workshop was chosen for the task as it had experience and required expertise in conversion of firing system from coal to oil. The workshop had already manufactured oil-fired steam locos for the Darjeeling Himalayan Railway and the Nilgiri Mountain Railway.

As part of the conversion work, the 15.5 tonne steam loco has been provided with twin head burner, combustion blower with air control, fuel pump, electrical control unit, fuel oil system accessories, and diesel oil tank.

The oil tank with a capacity of 800 litres has been installed in the bunker area where coal had been stored earlier. The 5 KVA generator set to power electrical items has been installed in the side platform of the loco which will run at a speed of 13 km per hour hauling four coaches. The loco has been given a fresh coat of polyurethane painting. The modification work has been carried out without affecting the heritage value of the loco, said P. Mahesh, Chief Workshop Manager. This is the first time that a narrow gauge loco has been sent for conversion of firing system from the Matheran Hill Railway, Mr. Mahesh said.

A technical team from the workshop will monitor the trials in the hilly Neral–Matheran section before the steam loco with oil-fired system is put into operation. The cost of conversion was Rs. 20 lakh. The loco was flagged off by S. Sundarrajan, Director, National Institute of Technology, Tiruchi, on the workshop premises.

The Neral- Matheran Light Railway was built between 1901 and 1907 by Abdul Hussein Adamjee Peerbhoy at a cost of Rs. 16 lakh. It is operated by the Central Railway now. Matheran is connected to the town of Neral, which lies at the base of the hills, by narrow gauge rail.

Third steam loco for NMR rolls out of Golden Rock

The third oil-fired steam locomotive meant for the Nilgiri Mountain Railway (NMR) was flagged off at the Golden Rock Railway Workshop here on Friday.

Comprising over 3,400 components, the steam loco belonging to the ‘X’ class has been manufactured at the workshop at a cost of Rs. 3.7 crore.

The workshop undertook manufacturing of 600 components in-house including oil-fired boilers to improve the reliability of the locomotive.

Similar to the second loco dispatched in March last year, the third loco has also been fitted with all welded boiler.

The Railway Board had entrusted the workshop with the task of manufacturing four oil-fired steam locos for the NMR, which has been recognised by the UNESCO as a World Heritage site.

The fourth loco is under production.

The need for manufacturing of new steam locomotives was felt as the old ‘X’ class engines procured from Switzerland and operating in the NMR section started developing problems leading to frequent service failures.

Initial efforts to get these locomotives imported failed due to limited number of sources and prohibitive costs.

The General Manager, Southern Railway, Rakesh Misra flagged off the third loco at a function held at the workshop premises.

The Divisional Railway Manager Manjula Rangarajan, Chief Workshop Manager P. Mahesh and senior railway officials participated.

BG locos converted to cape gauge for first time

For the first time, Golden Rock Railway Workshop has converted two in-service broad gauge diesel locomotives to cape gauge for export to Mozambique railways soon.

A host of modifications and additional features have been incorporated as part of the conversion work in the two engines to suit the operational requirement of Mozambique railways.

The RITES, a Government of India Enterprise under the aegis of Ministry of Railways, had entrusted the cape gauge conversion work to Golden Rock Railway Workshop after purchasing two in-service BG diesel engines from Southern Railway.

The cape gauge conversion works are in the final stage in the two locomotives which would be exported to the African nation through RITES in the second week of November.

Each of the two BG engines with 1,676 mm gauge distance was converted to cape gauge with 1,067 mm gauge distance to suit the Mozambique railway network.

The other modifications incorporated to improve the horse power of the locos include provision of modified cam shafts, upgraded fuel injection pump and larger displacement of turbo super charger of ABB make.

The horsepower of one of the loco has been upgraded from 2,400 HP to 3,100 HP, while it has been upgraded from 1,800 HP to 2,400 HP in the other.

The excitation systems of both locos have been converted from electronic type to micro processor controlled system. Similarly, the engine governing system has been changed from electro-mechanical type to micro processor based.

Provision of plate type lube oil cooler to improve the cooling efficiency of lube oil system, cyclonic type air filtration system, panel mounted brake system and installation of maintenance free nickel cadmium battery are among the other additional features incorporated in the two engines.

One of the cape gauge loco has an air conditioned cabin.

Though the railway workshop had converted several metre gauge diesel engines to cape gauge and exported them to Mozambique and Sudan, this is the first time that the organisation had converted BG engines to cape gauge for export, say officials here.

The workshop had converted 34 in-service MG engines to cape gauge and exported them to Mozambique and Sudan.

In addition to this, it had exported 133 MG locos to countries, including Malaysia, Tanzania, Sudan and Benin over the years through RITES and IRCON, another government company.

Engaged in a myriad of activities, the over 80-year-old workshop also manufactures steam locomotives for Nilgiri Mountain Railway and container wagons for Container Corporation of India.

Locos to Mynamar

The RITES had supplied to the workshop four more in-service MG diesel locomotives for export to Myanmar. The six locomotives already supplied to Myanmar were working satisfactorily, the officials said.

Railway workshop to make rubber plates for tracks

Engaged in major rolling stock activities including manufacture of container wagons and steam locomotives besides carrying out periodic overhaul of diesel engines, the Golden Rock Railway Workshop here will soon embark on a new activity of producing grooved rubber sole plates for track application.

The over 85-year-old nodal workshop of the Indian Railways has received in principle sanction for the latest activity from the Southern Railway headquarters.

The workshop would be investing Rs.1 crore sanctioned by the Southern Railway towards procurement of machinery to execute the new work using its well-established infrastructure and skilled technical workforce.

Milling machine, kneading machine, calendaring machine, and hand moulding machine are proposed to be procured for the manufacture of grooved rubber plates, each of which would be four to five millimetre thickness.

To start with, the workshop intends to produce five to 10 lakh grooved rubber sole plates per annum and supply them to the Southern Railway. Natural rubber would be used as one of the basic raw materials for the production.

The grooved rubber sole plates are placed between concrete sleepers and the track to absorb vibrations and shock when a train runs on the railway line. The plates provide a cushioning effect ensuring better riding quality.

The rubber plates were being supplied by private manufacturers to the railways, officials say adding that the workshop had evinced interest in producing them. The production is expected to start before this year.

Alongside approving the new project and earmarking funds, the Southern Railway has also sanctioned Rs.1 crore each for extending the electrical maintenance shop; carry out improvements to the toilets; and for the construction of a gas storage shed inside the workshop.

Housing over 25 different types of shops, the sprawling workshop also carries out periodic overhaul of air-conditioned and non air-conditioned passenger coaches besides constructing stainless steel body BOX-N wagons.
