Like all the original stations on the CLR, Marble Arch was served by lifts to the platforms but the station was reconstructed in the early 1930s to accommodate escalators.
Ligesom alle de andre oprindelige stationer på CLR, foregik adgang til perronerne på Marble Arch via elevatore, men denne station blev ombygget i begyndelsen af 1930'erne, hvor der blev installeret rulletrapper.
