These consisted of a long tanker with a silver walkway around side and on top. It was mounted on a pair of bogies.
The finish was either a silver tanker with a black chassis and walkway or a blue tanker with a silver chassis and walkway. Some of these wagons were stencilled with Texaco or Mobilgas, the US oil companies.
The bogies were different castings, the leading one had a pin and the trailing one had a towing slot.
