Question

Were there any other pre-grouping companies other than the LBSC that used the Westinghouse break pump?

Answer 1

most railroads from the late 19th century to the early to mid 20th century used the Westinghouse brake pump which is now known as WABCO (Westinghouse Air Brake Company)

Answer 2

The GER used air-braked stock from Liverpool Street and Fenchurch Street. This led to the LNER "Jazz Trains"

Answer 3

no, they are the only ones.

That particular brakepump causes nausea, so nobody wants to use it anymore.
