The line is now operated by 158/9 sprinter units. This means the 750Volt DC electric has no longer got a use. This may seem strange as most parts of the country are electrifiying lines. The reason for this is that "450 units" have 4 cars which are too long for Lymington Town Station. And South West Trains are not willing to remove a coach from a 450 unit. The only solution then is to use DMU 3 car sprinter units.
