block instrument
名詞
block instrument (複数形 block instruments)
- (rail transport, Britain) An instrument installed in a cabinet, used in block signalling installations.
- 1960 March, “Talking of Trains: Collision at Slade Green”, in Trains Illustrated, page 133:
- The line is signalled with upper quadrant semaphores and Sykes lock and block three-wire two-position block instruments. [...] The Inspecting Officer concludes that both signalmen must share responsibility for the accident by the irregular release of the block instrument, but remarks that the two-position Sykes instruments, although ample for maintaining safety under normal working, do not show clearly the state of the block section ahead.
