The railway through Bath Spa is reversibly signalled - trains can run in either direction on either track - but until now drivers haven't had stop boards when running the "wrong" way. This was corrected in February 2017 ready for a two-week period in April when all trains will need to use just one platform as each will be shut in turn to be realigned. This sign is being positioned for 4, 5 or 6 car down trains arriving on the up platform.
