Rail bridge joints have the same requirements as road bridge joints; with the further complications of greater loadings, larger dynamic movements, issues relating to track fixings and ballast.

Consideration to long-term durability is paramount as access for any routine maintenance is extremely difficult owing to the possible remote location, lack of road maintenance vehicle access, minimum working window and need for ballast excavation and retamping beneath continuous rail tracks.

When the rail bridge joints continue across the station platform the joint detailing issues relating to pedestrians, trolleys and light vehicles need to be considered.
