TRACTION SUPPLY INTO LIVERPOOL STREET CHANGES TWICE

Despite the economic supremacy of high-voltage AC, medium voltage DC catenary is still widespread in many countries. When British Rail converted lines east of London from 1.5kV DC to 50 Hz AC in 1960, a dual-voltage 25/6.25 kV system was adopted to keep the cost of conversion down. Subsequent work has reduced clearance specified for 25 kV so that conversion of former 1.5 kV DC overhead equipment to the higher voltage became practicable and BR expects to eliminate 6.25 kV by 1984.
