the timetable was cut back to ten round trips. Diesels started to appear regularly from 1962, both locomotive-hauled trains and diesel multiple units (DMUs). As of 2009, regular services operate between Minehead and Bishops Lydeard. The operating season runs from March to October, with infrequent operations from November through to February. Trains run daily during the summer but less frequently during the remainder of the season. Four regular timetables are run on different days depending on expected demand, varying from two to four trains in operation, each of which makes two round trips which gives between four and eight services each way. From February 2009 to January 2010, services were advertised on 243 days. Operating locomotives are based at Minehead and Bishops Lydeard and a spare is generally kept ready at Williton. During special events, an intensive service is operated and some workings continue through to Norton Fitzwarren. A few railtours each year come through from Network Rail using the connection near Taunton. The heritage railway also carries some freight traffic from time to time. At one time this was carrying stone for Minehead sea defences, in conjunction with Mendip Rail. In more recent years it has seen Freightliner-hauled Network Rail trains discharge old ballast at Norton Fitzwarren for recycling. Signalling The railway is separated into five nominal block sections: Network Rail boundary at Norton Fitzwarren (milepost 1651/4) to Bishops Lydeard: One Train Working (OTW). A "No Signalman" Electric Key Token (EKT) system is used on this section. The token is sent by car to when through trains operate from Network Rail. There are no intermediate loops, but three ground frame operated points to allow access and turning on the Norton Triangle. Bishops Lydeard to Crowcombe Heathfield: both stations have passing loops controlled by signal boxes. This section is controlled by an EKT system, as is the rest of the line. Crowcombe Heathfield signal box can be switched-out, creating a double section with the next block, with control then via a long section EKT system. Crowcombe Heathfield to Williton: both stations have passing loops controlled by signal boxes, with the block controlled by EKT. Williton to Blue Anchor: both stations have passing loops controlled by signal boxes, with the block controlled by EKT. Blue Anchor to Minehead: both stations have loops or facilities controlled by signal boxes. This section uses Electric Key Token (EKT) control and was the first section
