Heljan OO 1109 Mobil CharringtonS 201 Class B Oil Tank Wagon Red
Heljan OO Gauge B Tank 1109 MOBIL CHARRINGTONS 201 (red)
We anticipate these being models of the 35-ton glw (approx. 22 tons payload) oil tank wagons introduced around 1960, following on from Heljans' models of these wagons in O gauge.
The 35-ton glw wagons were equiped with suspension and vacuum train brakes suitable for running at higher speeds than the older 12-ton 4-wheel tank wagons, allowing block oil trains to travel safely at increased speeds.
