A large metro operator was researching ways to reduce bottlenecks that were causing significant delays at a busy station. With two routes dividing in close proximity to the station and a complex auto-routing system that required the use of a 30-second timer to release switches, trains would frequently back up when approaching the station.

The primary goal for any busy Metro line is to move passengers safely and efficiently. When consistent and unnecessary delays interfere with such goals, operators eventually look for improvements. In this instance, consultants were tasked with finding a solution, focusing on the legacy signaling system that was unable to offer relief from the bottlenecks.

The main issue leading to delays involved the switch located directly after the station platform being locked in its position for 30 seconds when the approach is occupied. Stopped trains that require the switch to be thrown in reverse position would have to wait for a 30 second ASR (Approach Stick Relay) timer to expire.

In conjunction with the operator, Frauscher was able to design a simple wheel detection solution that positively verifies when a train is berthed at the station platform, allowing a bypass of the 30 second timer. The berthing is verified within 5 seconds, allowing unnecessary dwell time to be saved each time a train takes a route requiring the switch to be thrown. The operator reported dwell time reductions of 40 minutes per day since the system has been in service.

Improved Controls

More granular detection of berthed trains; vital and fail-safe system

Reduction in delays

Allows for quicker response times at timing circuits, providing relief at bottleneck areas and a daily savings of approximately 40 minutes dwell time per day

Ease of Integration

The flexibility of the Frauscher system allowed for a seamless integration with the existing relay-based signal system

FAdC® at Uglerudnaya Station | Kazakhstan

AcelorMittal is the operator of the Uglerudnaya industrial railway station, located in Temirtau, Kazakhstan. The station features a total of 56 switches and 52 track sections to enable the smooth flow of train traffic. To ensure the safety of all trains, an interlocking system is used to establish secure routes for incoming, outgoing, and passing trains. This requires effective traffic management and a dependable train detection system to detect the presence of trains on the tracks.
