The 350/2s, having been ordered for LM to start with, don't have
shoegear of any sort.

But some have now been equipped for use on Southern?

No. Only 350/1s are used by Southern.

Ah! My confusion then. So why the suggestion that only some are converted
to be suitable for that role?


Only a subset of the 350/1s have been made ready and depot tested for DC
use, about 15 AIUI, out of the 30 in total. The 50% that do not have the OK
to work on DC wouldn't need a significant amount of work to do so. However
the whole sub class (350/1) is type cleared for DC running, the use by SN
only required route clearance.

For the 350/2s DC use would not be possible without significant additional
equipment being added.

Thanks for clarifying that.

What equipment? Just shoegear and DC fuses/circuit breakers etc, surely?

It is still a reasonably significant amount of external hardware across a 37
unit fleet, with 8 sets of shoe gear each.

That's 8 shoes each? Presumably 2 each side and each end of each driving
car? Just to be sure what you're counting as shoegear.

Yes, that's the normal 350/1 and 450/444 set up - 4 sets per end car.
