I often see London Overground Class 378s stabled in the sidings

or are these units doing test running? I did not notice until today
that these sidings do not have platforms.
Thanks, Dominic

It's all for night-time test running purposes - more specifically, for
the accumulation of fault-free mileage before they go into full
passenger service. I'll leave it to others more expert than I to
correct most of what I've said...!

AFAIAA Willesden does not provide "parking facilities" for DC line
trains which are not in for repair but Euston has done so since
Croxley depot was closed.
