    — Twenty-seven axle counters have been installed on the 49-mile East Suffolk Line, to improve level crossing safety and reduce waiting times at user-worked crossings. The Lowestoft-Ipswich line has 28 user-worked crossing/footpath level crossings where the signaller must give permission for people to cross. [...] Signallers use the axle counters to authorise users to cross at the user-worked crossings.
