It is true that this service has been curtailed at Farnham more than usual in the last few weeks, but this has not been done to save money on drivers and guard wages.
Network Rail have recently completed two significant pieces of infrastructure work: a re-railing job and a bridge renewal. This has meant that they have needed a higher number of engineering "possessions" of the Alton branch in recent weeks, both at night and at weekends.
The 0040 Woking to Alton service has terminated at Farnham so that the train can be worked directly into the depot at Farnham, leaving an adequate amount of time during the night for the infrastructure engineers to take possession of the line and carry out their work, thus minimising the number of possessions required.
With the completion of these works, the 0040 Woking service should be able to operate with its normal level of reliability.
