[[File:9102 nlr 050807 d.adkins.jpg|thumb|right|[[British Rail Mark 2|Mk 2]] BSOT number 9102 at the [[Northampton & Lamport Railway]]. Converted for use by a [[Motorman (locomotive)|Motorman]] in [[push-pull train]] operation.]]

A '''Brake Standard Open (Micro-Buffet)''', often abbreviated to '''BSOT''' or '''BSO(T)''', is a type of [[railway carriage]] used by [[British Rail]].

These coaches were converted from a [[Brake Standard Open]] (BSO), by replacing one passenger seating bay with a counter for serving food, and space for a trolley for light refreshments. The toilet was removed and the space converted to a steward's prep-room and store.

Two batches of coaches were converted, as shown below.

These coaches are no longer in scheduled main-line services, the last being withdrawn in the mid-1990s. However, several coaches from both Mk1 and Mk2 types have been preserved on [[heritage railways]], or are used by charter companies. These are detailed below:
