What I never thought about until now is that the tracks

District Line tracks, are mixed gauge in the lithograph.
I have never seen anything to suggest that broad-gauge
trains used those tracks. Does anyone know how far
toward South Ken the broad-gauge rails ran,
and whether they were ever used?

They didn't, as can be seen if you take a look at the tunnel
width at the junction. The lithographer used artistic licence.

Was there any device to prevent broad gauge trains attempting to go the
wrong way?
