That first Tiger looks like it has it's "travel" tracks installed. They were more narrow & they had to remove the outer wheels. It was to fit on trains.

You can see the 2nd road wheel in both pictures looks normal, just the 1st, 3rd, 5th etc outer ones have been removed.

I suppose in an urban environment the travel tracks would make sense to have, being lighter & not needing the reduced ground pressure....






Does anyone know if many Tigers fought with their travel tracks often?
