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.
