Bachmann’s LT red pannier tank is a super little model. However, as it is derived from the GWR/BR version of the model it is lacking a couple of key details from the prototypes. The kit comprises of 1x Tripcock apparatus for the left-hand running plate, and 2x screen curtains for the cab, all 3D printed in plain resin.
The curtains served as blowback screens for when the locomotoves were working in tunnels. Tripcocks are a safety feature of the London Transport system, where if a train ran a danger signal, the tripcock would be hit or “tripped” by a lineside apparatus, which would force the brakes to be applied to the train.
