I am planning to attempt IRSE examination for module B. There are 4 modules altogether, with module A being a prerequisite for the other modules. The idea is module A covers the overall and asked about ‘everything’ about signalling but at a surface level. Module B, C and D focus deeper, with each module has…
Currently it seems that a car, is the ‘bad guy’ in the environmental sphere. Anytime effort or plans to reduce CO2 emission (COE) is put forward, the imperative is always to reduce car usage, among others.
Recently I passed the IRSE Module A, and I thought I’d be sharing my thoughts and opinion about it, while it’s still relatively fresh in my mind. This exam, and its other module, has always had a ‘bad’ reputation, being touted and taunted as a difficult exam, but after sitting for it, I think that…

An accident could happen if the signaller sends a train to a track that is occupied. Hence the development of track detection. Two of the most well used track detection is track circuit and axle counter.
