Carriage 120 is an all third saloon carriage in the Super Barn series.
The underframe was nearing completion at Boston Lodge in early August 2017. By the end of June 2018 the carriage was largely complete and the old 120 was withdrawn to release its bogies for the new carriage. It entered service on the 17th July.
