Humps on tube lines
The Central London Railway began with Camel Backed Electric locomotives
hauling unpowered carriages. In order to improve efficiency distinct humps (mini summits) were built into the track profile at stations from Notting Hill to Liverpool Street - incoming trains were slowed by the rising gradient whilst outbound trains were hastened on their way by the falling out bound gradient. The heavy unsprung locomotives were soon replaced by multiple units with intermediate powered bogies. Does anybody know if humps are still built into station tracks on new tube lines. |
