One could reasonably wonder what is going on here? Have we decided to simplify AVLR operations by fitting some form of remote control, thereby saving all the faffing with running the loco round the train at each of the train? Tempting, but wrong. This is testing the Portable Air Brake Panel (better names are doubtless available). The PABP is intended to allow some of the locos which are not fitted with a permanent air brake installation to be used with the passenger train. Supported by all the necessary risk assessments and the like, this new piece of kit will be the centrepiece of the Diesel Delights event on October 7 & 8. The event will see some of the Trust's vast collection of historic diesels being given a chance to haul passenger trains, for the first timer ever. So, if you want to see an interesting piece of railway brake technology, plus maybe some trains, put the date in your diary today!
