I visited the sidings twice in the 80's, the second time there were 101 vehicles present, but this first visit, on August 4th 1987, contained a more varied selection of stock, including a shunter, notable for it's absence in 1988. Here's the list of vehicles present on that first occasion:

08666
1740, 5123, 6408, 6411, 7113, 7191, 7916, 7928, 18808, 18837, 18862, 19452, 19536, 19555, 35461, 59230, 59794, 80654, 80663, 80707, 80752, 80789, 84086, 84092, 84096, 84433, 92176, 93107, 93138, 93218, 93233, 93417, 93441, 93539, 93542, 93555, 93560, 93563, 93571, 93584, 93592, 93594, 93673, 93688, 93764, 93769, 93781, 93798, 93808, 93813, 93854, 93866, 93907, 93919, 93941, 93942, 93962, 93969, 94063, 94070, 94073, 94076, 94077, 94078, 94112, 94173, 94176, 94219, 94239, 94298, 94303, 94307, 94314, 94335, 94731, 94792, 94817, 94881, 94892, 94899, 94919
99710/18767, 99711/18857, 99712/25893, 99713/19013, 99714/7187, 99715/35737, ADM44404.
As can be seen, if anyone's looked through this list, 23 4-wheeled CCT vans were to be found, along with a couple of DMU cars & a few oddities, like the LM inspection saloon. A very interesting place (if somewhat short of motive power!) the likes of which don't appear to exist any longer. The yard's staff were only too pleased to allow my visits, very accomodating; sadly also a thing of the past. Ah, memories.....

Red Bank sidings are long gone, lifted in the ealy 90s, along with the line from Victoria East jct to Thorpes Bridge Jct (near Newton Heath).
