British Rail Class 499 is a TOPS designation allocated to London Underground electric multiple units that operate on Network Rail tracks for part of their journey. The designation was previously used by a class of luggage vans on British Rail's Southern Region, but was reused by Railtrack from 1994 for its current purpose. This does not involve any renumbering of the stock involved, and is only for electronic recording purposes.
