The South African type ZB tender was a steam locomotive tender from the pre-Union era in the Cape of Good Hope.
The Type ZB tender entered service in 1892, as tenders to the second batch of 7th Class4-8-0 Mastodon type steam locomotives to be acquired by the Cape Government Railways. These locomotives were designated Class 7 on the South African Railways in 1912.[1][2][3]
