PLPR-4 set vice NMT, with top and tail Colas orange power cars, a first time sighting of 43257 in Colas orange.
43277 Safety Task Force leading 1Q70 16:45 Gorgie Jn (in practice Haymarket platform 0) - Slateford, into Aberdour.
A closer view of 43277 as it passed through.
43257 on the rear - I have seen this power car in East Coast, Virgin, LNER and two Colas guises. The coaches were believed to be 9481 + 72639 (with PLPR light) + 977997 + 977974 (nearest), which are often in the 1Q5x Eastleigh based test trains.
