Class 67 [Updated]

The Class 67 is a mixed traffic locomotive originally intended for 125mp/h operation on postal trains and other exclusive services like the Royal Train [1]. By the time they had arrived from Spain the intended post services had gone so they have been involved on charter, passenger and other general duties instead. When they arrived they were restricted to 110 mp/h because of the high axle load but bogie modifications have restored their design speed. Problems with exceeding the loading gauge also delayed their introduction into service.

Information
Number built: 30
Built: 1999-2000
Builder: Alstom Meinfesta / General Motors
Engine: GM 12N-710G3B-EC diesel
Power: 3, 200 hp (2, 386 kW)
Wheel arrangement: Bo-Bo

A major duty for the Class 67 has been on Chiltern Railway's expresses from London to the Midlands though they were replaced by newer Class 68s. They can often be seen around the network but maybe arn't utilised heavily enough to justify the high cost of building and bringing them over.

Network Rail High Definition Switches and Crossings Video Inspection Train

The fleet of Windhoff built Multiple Purpose Vehicles (MPVs) perform a wide variety of departmental duties for Network Rail and supporting companies. One specialist MPV is the High Definition Switches & Crossings Video Inspection Train DR 98008 which originally was part of Network Rail's fleet of Overhead Line MPVs[1]. This is a double cab single car vehicle (most MPVs have cabs at one end only and operate in pairs).

Information
Number built: 1
Built: 1999-2001, 2012
Builder: Windhoff
Engine: 2 Railpac diesel engines
Power: 710 hp (530 kW)

It is used by Network Rail's Asset Information department with visual inspection equipment especially for switches and crossings (pointwork in other words). It is also fitted with a version of the Plain Line Pattern Recognition (PLPR) system, which compares video footage of the track with a database of track fixings so broken fixings and irregularities can be detected [2], for switches and crossings. It is also fitted with a track geometry system.
