Sand button pressed in
The freight Chord linking Dollands Moor to High Speed One is only used once or twice a day at most and therefore is always a little "slippy" Add in the fact it is so steep its a struggle for even a class 92 to get up with a train. The in cab signalling speed up here is 30 KMH and if the speedo were to go over 35 KMH then the TVM would sense it and apply the brakes. So if the wheels start slipping the speedo goes over 35 KMH and the brakes would apply so the best option is to "sand" the rails on the climb whilst applying full power to actually get the train up and over the hill so to speak without the wheels slipping. 92 011 is seen on full power and sand being applied as the sun rises over D Moor on 6L23 0528 D Moor-Ripple Lane Exchange Sidings via High Speed One.
