LNER (London North Eastern Railway) operates trains on the East Coast Main Line in the UK. Their speed depends entirely on the type of train:
Azuma Trains (Class 800/801/802)
These are LNER’s current flagship high-speed trains.
Maximum Design Speed: 125 mph (200 km/h) on the existing East Coast Main Line.
In-Cab Signalling Stretch: On a specific upgraded section between London King’s Cross and Leeds (via the ECML and part of the Transpennine route), they can run at up to 140 mph (225 km/h). This is currently the fastest regular service speed in the UK.
InterCity 225 Trains (Class 91 Locomotive + Mark 4 Coaches)
These are the older electric trains being phased out but still occasionally in service.
Maximum Speed: 125 mph (200 km/h).
Important Context: Linespeed vs. Service Speed
- The maximum linespeed on most of the East Coast Main Line is 125 mph. Even the Azumas are limited to this outside the special 140 mph section.
- Average journey speeds are lower due to stops, curves, slower sections through stations, and other traffic. For example, the fastest London to Edinburgh service averages about 100 mph for the 393-mile journey.
International Comparison
- While fast for the UK, these speeds are not as high as dedicated high-speed lines like those in France (TGV, up to 200 mph / 320 km/h), Japan (Shinkansen, up to 200 mph),
