The lack of recent news does not reflect a lack of recent progress. This report focuses on ‘new’ construction. KS4415 has never had a ‘drag box’ per se, merely couplings and buffers attached to the buffer beam. In early 1929, KS4415 was fitted with chopper couplings to allow it to be used on passenger trains on the WHR. This is the period the restoration aims to represent. How the chopper couplings were fitted is unclear. Getting the coupling arrangement right is essential for the safe operation of the locomotive so we are shamelessly adopting current technology. To provide an idea about what we are currently fitting, here is ‘the answer’, in this case fitted to new FfR observation car 152.
|Dragbox Assembly Car 152|
|One of the crossheads for KS4415|
|The bufferbeam marked out for the new slot |
to accommodate the coupling
|Spare’ holes welded up, and new slot cut|
|A doubling plate has been fitted inside the frames|
|Having welded the old holes up Matty Wolstenholme drills|
a new row of holes. These will be used to rivet a pair of angles
inside the frames which will carry the dragbox.
|New holes, meet old holes|
|The angles used to fit the drag boxes to the frames |
have been riveted in. The two bars labelled ‘top’ and ‘bottom’
are the start of the dragbox and are bolted to the angles.
|The rear unit is more bijou.|
