LO Class 378 at Purley?

[Class455]

Whilst on a train at Purley at around 12:30 this afternoon, I happened to see London Overground’s 378232 pass me on Platform 4 heading south. It was showing London Euston on the destination blinds. Any idea where it was heading as I can’t find anything on RTT?

It is testing for new workings it will be doing, I think as 4 car instead of 5 but not certain here's the paths same as yesterday
