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.
| Number range | Type |
|---|---|
| 9000-9017 | Mark 1 |
| 9100-9107 | Mark 2 |
These coaches are no longer in scheduled main-line services, the last being withdrawn in the mid-1990s. However, several coaches from both batches have been preserved on heritage railways, or are used by charter companies. These are detailed below:
