THE most technically advanced train of its type in the world, Network Rail’s ‘NMT’ flew through Pembrokeshire this week at 125mph.
The ‘New Measurement Train’, affectionately known as the ‘flying banana’, is a unique, high-tech machine equipped with the newest measurement systems, track scanners, and a high-resolution camera to help measure the condition of the tracks.
Covering 20,000 miles of track the monitoring fleet slot between timetabled trains so there are no delays or disruption as a result of the work. A spokesman for Network Rail said: “The train ran through Pembrokeshire on April 14 before moving up to Derby in the evening. The train passes through different areas every few months or so as it travels up and down the UK monitoring the tracks.”
