Monster Machines: This ‘Flying Banana’ Keeps Britain’s Trains From Running Off The Rails

The UK rail system includes more than 16,000km of track, which, until relatively recently, had to be inspected at a walking pace. This laser-blasting, track-inspecting locomotive, however, does so faster than a speeding bullet (train).

The New Measurement Train (NMT) is one of 17 track-inspecting trains employed by Network Rail, the UK’s government-owned rail system. Its bright yellow livery and blistering 200km/h pace earned it the nickname “the flying banana”. It sandwiches two messing cars, two operations cars and a meeting car between a pair of MTU V16 4000 R41 diesel-electric engines.

The operations cars are packed with sensory equipment designed to spot the slightest faults in the tracks. This includes a Track Geometry System, which measures the relative orientation between each pair of tracks using laser track scanners and seven high-res video cameras; an overhead line inspection system; and the Plain Line Pattern Recognition (PLPR) system, which looks for “abnormal join gaps, abnormal expansion join width, railhead defects and cracks, fishplate defects, switch area defect recognition, sleeper defects, missing fasteners and weld clamps that should have been removed,” according to the system’s creator, Rail Vision. Basically anything that could be big trouble, either right now or a few days, months, years down the line.

While the other track-inspecting trains in Network Rail’s stables only travel about 50km/h, the NMT’s 200km/h pace leaves them in the dust at more than double the speed limit of UK highways. At that pace, the NMT was able to spot a whopping 33,000 faults requiring additional inspection in September of this year alone. [The RegisterRail VisionNetwork RailWiki]
