The Victoria line remote track circuit monitoring system keeps track of the degradation of signals, and predicts repairs before failures happen. The interface is installed in the Victoria line control room.
The impact of a signal fault is very high. While a fault to a train can be problematic, it is invariably possible to manoeuvre it out of the way of other trains. A signal fault, on the other hand, affects all the trains passing through that signal.
We initially looked at off-the-shelf remote monitoring solutions, but quickly believed we could produce our own system at an equivalent or higher quality and at a cheaper cost.
We broke the system down and used industry-leading organisations to help develop individual elements, or found solutions in-house. As a result, we own the entire intellectual property and have helped to keep our workforce highly-skilled and at the forefront of technological development.
Goals, outputs and benefits
Since introducing the system on the Victoria line, there's been a 58% reduction in customer hours lost due to track circuit issues. This amounts to over 70,000 hours recovered - and a saving of £600k - every year
We are now looking at expanding the system to the Central line, which has an older generation of track circuits than the Victoria line. This is a good example of how we are taking existing Underground technology and making it work with the internet-of-things
