When the '46s were sent over, at first, only two were sent over (one to Pueblo, one to NJT), so that if a problem was discovered (none were), the entire fleet wouldn’t have to be sent back. It seems that they are doing this again. This is more preferable than having 46 locomotives shipped back to Germany in order to correct problems.
Honestly, why wouldn’t they fix them here?
Awesome:
(I think they used the FP7 Locomotives).
Actually they were F9 variations, and the modern ones are built by GE. They are dual mode Genesis units. Using third rail.
In the UK we have some electro-diesel locos of Class 73 which live on on the privatised network, and some in preservation. Designed for the Southern Region 750v 3rd rail electrification they can draw power from the third rail or use a small diesel electric setup when away from the electrified system. Currently the 73s are used on infrastructure and short freight normally although they have powered enthusiast specials. The preserved examples all run on diesel only as, despite the work that has been done in preservation, electrified preserved railways don’t exist (never say never, of course).
The government has plans for some high speed trains with a diesel electric unit at one end for use away from the wires, and a straight electric at the other end of the train. I suppose this ‘hybrid’ doesn’t really qualify. Hitachi seems to be the preferred bidder and assembly should take place in the UK. Exacty where it will happen has not been decided yet.
This plan already has some application planned for the NJ Transit. If you read the NJ T proposal for the dual mode type operation and also the ACEs (Atlantic City Express) is being operated this way however ACE trains do swap directions when changing from diesel to electric. But NJT is planning to operate other trains this way.
I rather thought the ACES arrangement was temporary until the new true dual-mode locomotive order was delivered.
