Does anyone have the values for 139s (e.g. dwell times)?
On a separate note, I'm thinking a 139 may be the answer to Melksham's prayers? If a crossover was installed just west of Chippenham, and some bi-directional signalling, one of these could run on an hourly basis all day between Chippenham-Westbury. This may be a viable solution to the poor level of service on this line. Does anyone think this could work, and is a good idea?
