Prototype Notes

What was a GWR Mica B?

The Mica B was a Great Western Railway insulated refrigerated van designed primarily for perishable traffic, especially fish, meat, dairy, and fruit.

• “Mica” = GWR telegraphic code for a refrigerated/insulated van

• “B” = the second major design variant

They were among the most important non-passenger vehicles on the GWR.

 Design & construction

Mica B key features:

• Insulated wooden body (not iron like Iron Minks)

• Double-planked walls packed with insulation

• White-painted roof (to reflect heat)

•  Doors on each side

• End ice hatches for loading ice

• Vacuum brakes

• 12-ton capacity

• 9 ft wheelbase (later builds varied)

Unlike later BR fridge vans, cooling came from ice, not mechanical refrigeration.
