Think of it more as being able to apply the appropriate level of power for the load being hauled. For instance some train will only need a single Schoma at front and rear (say two to three wagons). Others will require a pair of Schomas at front and rear. A rough rule of thumb is that two electric Schomas equals one Battery Loco.
The first two (2 and 5) should be back in London around December 2014 / January 2015, but being prototypes there may be some variation to that timescale.
Regards,
Dan

I would have thought that visibility from the single cab would have been an issue, especially in a tube tunnel.

What are the benefits that electric Shomas will offer over yesteryears solution of Ballast Motors?

What are the benefits that electric Shomas will offer over yesteryears solution of Ballast Motors? Having batteries they will be able to operate with the power 'off'. It will be interesting to see what of the original loco will be left beyond the cab and frames.

This may be slightly off topic, but I wondered if the Schoma Diesels were ever able couple up to Tube Stock, electrically and with air as the Battery Locos are?

Schomas 1 and 12 are currently fitted with full Wedgelock couplers and brake control interfaces to couple to 95TS and 96TS, although I think it needs work before it could be used properly again. Schomas 2 and 3 are fitted with emergency Wedgelock couplers, like the Battery Locos, but are unable to control the brakes on the tube stock being coupled to.
Battery Locos can only ever couple up physically and only tube stock pre-73TS can have their brakes controlled by having air hoses connected to the Train Line and Main Line (like we did with the AIT in April).
Regards,
Dan

Quite a lot of noise for a battery loco!

Provably gear box noise on the drive from the traction motor FISH7373

These loco's have a very short wheel base and may become gapped unless used as pairs and a jumper cable is used between the two loco's.

They are battery locos - why would it matter if they got gapped? Engineers trains have to travel from Ruslip to the works site on traction current, when they arrive the current is switched off. This is a safety measure to protect staff. The Locos only work on battery in the protected work site.

Does anyone know what type of batteries they are fitted with? It would also be nteresting if Tesla went into the rail narket with their battery technology.

This is a safety measure to protect staff. The Locos only work on battery in the protected work site. Maybe I am missing something here, but if one got gapped surely the answer is to switch to battery for a few metres to get to a live rail.

This is exactly what would happen in that situation. Its very easy to swap to battery power.

Provably gear box noise on the drive from the traction motor FISH7373 No gearbox as such is fitted, two motors positioned back to back drive directly into each one of the original Schoma axles via short cardan shafts.
