...and then shipped to Turkey for re-erection broken down into 23 crates or cases: 1 x frames complete with cylinders, 8 x separate pairs of wheels, 1 x boiler, 1 x tender underframe, 1 x tender tank; 11 further cases in which all the smaller parts were packed. (The state of available shipping and port cranes in Turkey forced this method, there weren't enough ships regularly available with a deck crane to lift the 70 ton load of the 'dry' locomotive, nor the necessary dock cranes of sufficient capacity in Turkey.)The loco that never arrived. This 8F was built by the North British Locomotive Company in December 1940 ...
The replacement 8Fs that were sent to compensate for those lost at sea were conversions and retained the compressor on the right hand side - also the Vacuum ejector exhaust was not removed - one of these locos is now at Bo'ness on the SRPS site.
The description of the problem suggests to me this might be a split chassis mechanism B1? (Simple diagnostic, won't have a DCC decoder socket or NEM coupler pockets.)I have a Bachmann B1 that has developed a 'wiggle'. I've swapped the chassis with an LNER liveried one I don't run on the layout and it is fine, but any suggestions as to a cure - it it just wear and tear? Would replacing the axles help?
I've also had instance of the plastic wheel centres distorting and fouling the coupling rods. That loco also got failed valve gear and was withdrawn for spares.
Indeed, however your model is upgraded beyond anything the LNER did to the V2, by the double Kylchap ejector exhaust which has increased the boiler power output potential significantly. I would suggest that the appropriate tender is a four axle type, mainly for the extra water capacity on a long high speed run....I haven't decided about the tender yet. The original outline shows a standard 6 wheel tender.
