I see that TfL has now signed the contract for the 57 new cars to
extend all the Class 378s to five cars:

Did they buy some extra whole trains too? The report doesn't say.

I believe not. The original project authority had scope for a couple
of extra new trains but this has not been proceeded with at this
stage. If it had then I would expect it would have been clearly
stated. I suspect the cost for such a tiny run is too high to be seen
as value for money. Bombardier are (allegedly) notoriously "difficult"
about prices for small production runs.

My wild speculative view is that TfL would prefer to wait to see if
they get approval for GOBLIN electrification. That will obviously need
new EMUs, most likely 378s, so it would decide then if it wanted to
add to the overall fleet to help add extra services on the existing
electrified network.

One thing I did find interesting is that the 5th cars were an option
on the previous contract for supply of the 378s so clearly someone had
some foresight!

If there was an option that should provide reasonable prices for the extra
cars. Perhaps not for whole units, though. Cabs are expensive so just four
in the whole order for two extra trains would probably be expensive.
