Also correct, but that 2nd batch of 317s was never related to Snow
Hill / TL and again can't be counted as part of that fleet.

I assume they were 317s for no more reason than that was the current
type in production - this is the same reason NSC got extra 6 x 319s as
Cig/Vep accident replacements - they were the only third rail DC
capable type in current production.
