What is "klub-u"

KLUB is the name of the modern Russian train control systems. The abbreviation "КЛУБ" stands for , Integrated Train Protection System. The most common variant is KLUB-U where the U stands for unified .

KLUB-U in-cab signalling systems are able to decode the track-side ALSN codes (Continuous Automatic Train Signallisation) which is similar to RS4 Codici (comparable to Pulse Code Cab Signaling in the US). In the newer ABTC-M block control the KLUB-U systems decode signals by TETRA digital radio including a remote initiation of a train stop. In those areas the train position is derived from a satellite navigation system ( GPS or GLONASS). The ITARUS-ATC connects the KLUB-U in-cab system via GSM-R digital radio with the ERMTS Level 2 RBC block control.

The KLUB-U systems are capable for high-speed tracks like that of the Velaro RUS (Sapsan).

The variant KLUB-P is restricted to cab signaling without track safety equipment. It is only used in category-II trains (including special cars and shunting movements). The variant KLUB-UP is allowed for category-I trains (including passenger transport) where it replaces the cab signaling of ALSN.
