Bourne End is a terminus but effectively acts as a through station, with the driver having to change ends to continue to the next station. During peak hours service frequency is increased by having two trains work the line, each using Bourne End as the terminus: one runs Marlow – Bourne End and one Maidenhead – Bourne End, with passengers changing trains at Bourne End. This service pattern is needed to meet peak-time demand, as the platforms at Bourne End are not long enough to accommodate longer trains and there is no passing loop on the branch line to allow two trains to run the full route between Marlow and Maidenhead. While Bourne End has two platforms, platform 2 is only accessible from Maidenhead and not from Marlow, and so cannot be used as a passing loop.
