The second sleeper was more challenging as the original bogies had been misplaced. Based on the bogie mounting points, it was surmised that this sleeper used conventional 8-wheel, opposed to 12-wheel, bogies. Originally, old Hornby bogies were fitted but this resulted in poor running as the couplings were slightly too recessed. Following the great melt-down, when next door's tree fell through the shed resulting in considerable sun damage to rolling stock when the roof was being repaired, we had several spare Lima bogies. These bogies proved a more suitable alternative and, after multiple adjustments to their height, were subsequently fitted.
Building up the rake required a composite and full second carriage. We had a spare Bachmann Mk1 full second which was prone to poor running. Instead of fixing the coupling issue, the Hornby bogies discarded from the sleeping car (mentioned above) were fitted. This resulted in faultless running of what is otherwise a beautiful model.
A search through an old box revealed an original Triang Mk1 composite carriage with old non pin-point bogies. We sourced a pair of Lima bogies as replacements and, though successful, their mountings would have required minor modifications to fit the interior. Luckily, we had a Triang sleeping car with no interior fittings, so a swap was possible. Following a paint job to the interior, the carriage was ready for service.
A Gresley buffet, which might arrive one day and a Stanier full brake will round off the final rake.
The new carriages, in an interpretation of the final rake were test run in the videos at the bottom of this post. Photos of the work can be found below.
