89 is a GWR 4-wheel Riding and Dormitory Van. In service these ran paired with 6-wheel Tool vans such as [[GWR 66 Breakdown Tool Van | GWR 66]], and were stationed at GWR loco sheds. The Tool and Riding Van pairs would be required to attend mishaps as fast as possible and were vacuum-braked to allow running at near express speeds.
