Each day, Chiltern Railways (in conjunction with Vintage Trains) will be running 3 special steam trains in each direction between High Wycombe, Beaconsfield, Gerrards Cross and London Marylebone. This is a rare opportunity to travel by steam on the Chiltern main line behind 2 different former Great Western Railway 'Hall' class locomotives, which will be 'top and tailing' the train, one at either end.
