The first vehicle is very interesting as it is a H2/D42 Dreadnought tea car.
In 1913, two D42 standard brake thirds number 3467 & 3472 were rebuilt with extra doors by replacing two compartments as a kitchen/buffet area and reclassified as H2 (reusing the diagram number from the clerestory diners which had long been rebuilt to other diagrams by this time). They remained in this condition until 1936 and 1937 respectively.
