Tourist Standard Open Buffet or TSOB cars are railway passenger carriages used in the United Kingdom originally by British Rail and by its successor railways following privatisation.
TSOBs numbered 10401-10406 are in use with the privatised British railway company Abellio Greater Anglia.[1] These vehicles have been designed to accommodate additional passengers beyond those able to be accommodated by the Standard Open-class carriages upon which they are based. There are about 62 seats in this coach and there are 8 priority seating spaces for the elderly and/or disabled.
