A signalling problem is causing long delays for commuters between Maidenhead and Marlow this evening - with the problems expected to continue into tomorrow. 

Fewer trains are able to run on Great Western Railway between the two towns and trains are terminating at Maidenhead because of the ongoing problem.

Angry commuters were forced to use replacement bus and taxi services this morning and GWR are expecting the problem to continue until midday tomorrow. 

An hourly shuttle service is operating between Maidenhead and Marlow.
