With the introduction of 5 car 377/6 and 377/7 sub classes many of the suburban services were altered to run as 10 car. With the 4 car sets the addition of 2x377/3 had the same effect and this small sub class of 3 car units were removed from Coastway services and redeployed to Selhurst being replaced in turn by refurbished 313/2 units.
Here we see a 10 car 4+3+3 formation approaching Balham - Gateway to the South! - headed by 377430 27th February 2014
