From 2009 the railway adopted a letter-coded timetable system with "R" being the standard four trains in each direction each day as previously, with a variety of other codes ranging from "S" with a six train service to "T" covering the commuter trains in T.T. week and "U" for evening services commonly operated on a Thursday in peak season.  The monthly Commuter Club trains are designated as timetable "C" supplementing the days' services and an experimental "V" schedule operated some years.  This page will be expanded as time allows.
