I dont quite think you know what a hot box is 1288.
they are positioned next to the rails, on the outside.
I think he's right Simming, the 225 sets have inbuilt monitoring systems.
Hot boxes are a nightmare, you need to dump at the very nearest location, not the most convient, so places like goods yards that haven't been used for 30 years. Then you need to go and fit a wheel skate {a craddle to move the siezed axle}, then you need to skate it to the nearest lifting depot {Eastleigh, Bournemouth, Wimbledon, Brighton etc}, 5mph across points and crossings, 25mph on plain line
