On my usual walking route into town I pass over a tunnel mouth. Unusually the railway passes directly under the centre of town and under the 12th century castle. Reckon they'd get away with that today? Peering over the parapet you get a view of an infrequently modelled piece of trackage - the welded rail expansion joint. the operation is fairly obvious - the rail end is free to slide in the two chairs, is bonded electrically with the wiring and the four linking sleepers are bolted together with old B/H rail. Nice to see that the Southern Region (it must be returning soon) still throws nothing away. Models of this anywhere?
I think Peco used to do a moulding for this.
