COMMUTERS should double-check trains before hopping on their usual service to work tomorrow - especially if travelling with two wheels.

Great Western Railway enforced its summer timetable today, which could affect passengers across the county.

It has not detailed which services will be altered but has advised customers to check using its journey planner. 

From tomorrow the transport provider will also bring in new rules about carrying bikes onto high-speed trains, requiring cyclists with non-folding bikes to book a space at least two hours before their service departs.
