Diesel hydraulic to battery electric.

Recommended Posts

The 12 Schoma diesel hydraulic locomotives are being/have been converted to battery electric, film here of one of these locomotives being tested using a class 31 as a test load/load bank >>

How is the project going? I heard that it has run into difficulties and some locos are to remain diesel?

From memory only 6 or 8 were converted and found to be 2 ton over weight so have all been stopped and not turned a wheel since they come back 

2 have gone to Eastleigh to see if they can be modified to run as a single loco (2 permanently coupled running as one ) but after driving them on diesel and electric I found them to be under powered after the conversion 

I can’t see them ever running in revenue so will probably end up sold or scrapped but stranger things have happened

Can I ask please whether adding 3rd/4th rail shoes to raise the working voltage for electric would improve the traction performance of these locos.

If the are to be used on the underground they would be fitted with collector shoes. The existing battery locomotives charge their batteries from the conductor rails whenever they are on electrified track.
