Abstract: This paper describes an interim circuit with contact function between Lhasa station and Lhasa loco depot during the Lhasa station renovation. Based on the standard circuit, conditions of DJ shunting signal are added in order to achieve consistency between indoor and outdoor display and ensure the fail-safe feature of the circuit. After the renovation, the interlocking conditions between the loco depot and the station are realized by the liaison circuit between yards. This paper can provide a design reference for similar projects in the future.

Key words: liaison circuit with loco depot, liaison circuit between yards, CBI, interface circuit
