769450 out on driver training today seen it go past Leyland cam on 5z40 and 5z41.
From RTT, these seem to be the first two of a planned series of ten ECS workings, all under wires:
5Z40 Springs Branch Stabling Sidings (dep 1249) to Blackpool North (BPN)
5Z41 BPN to St Helens Central (SNH)
5Z42 SNH to BPN
5Z43 BPN to BPN (reversing at Kirkham & Wesham [KKM])
5Z44 BPN to Wigan North Western (WGN)
5Z45 WGN to BPN
5Z46 BPN to BPN (reversing at KKM)
5Z47 BPN to Preston (PRE)
5Z48 PRE to BPN
5Z49 BPN to Springs Branch Stabling Sidings (arr 2237)
But it appears that 5Z41 was terminated at Springs Branch (running 7L) and the other eight workings were cancelled.
