Callow Lane is normally set in the late 1950s to 1960s period, but here we see a scene from early 1953, where a train of coal empties is returning to South Wales from Westerleigh Yard. What is unusual about this is that the booked 56XX had failed on Ebbw Jct shed earlier that morning and the only other available loco - a 67XX pannier - was deemed insufficiently powerful to haul the train up the bank from Callow Lane to Coalpit Heath West Jct and, of course, through the Severn Tunnel.
Eventually Control found a replacement 0-6-2T at one of the other Cardiff sheds. No.155 was one of a small class of Kitson locos built for the Cardiff Railway and the only example to be rebuilt by the GW following the Grouping. 155 had a 'heavy general' in 1949 and emerged from Swindon resplendent in BR black livery, albeit without any crest of other markings on the tank sides. It ran like this until it's eventual withdrawal in May 1953.
Here we see the loco passing over the level crossing and our excited photographer followed the train as it slowed for the Up Starter, which was a danger, due to a down ballast train in the section from Coalpit Heath:
The down train consisting of a 56XX and a rake of herring ballast hoppers from the Forest of Dean draws onto the Down Main from the single line:
As described elsewhere, there are no kits available in 4mm scale for 155. The body was built by John Farmer (aka Charon), using a Bachmann 56XX cab and bunker, a 22XX boiler and scratchbuilt side tanks.
I sorted out the chassis, eventually using a Bachmann 57XX chassis converted to P4 with Gibson wheels. The wheelbase is a little off but there is no RTR chassis option with the exact wheel spacings and I considered this preferable to a full scratchbuild. I then painted and weathered the loco.
