 These connections allowed fast Bristol trains to overtake slower trains that called at Creech St Michael Halt which only had platforms on the outer (Bristol) tracks.Slow trains between Taunton and Castle Cary ran via Durston station to on the Yeovil Branch Line where there was another junction with the Castle Cary route, which meant that they ran through Cogload and Creech St Michael on the outer tracks.On 29 March 1986 the two Bristol lines were taken out of use between Cogload and Taunton, returning the line to its original two tracks.
