DCC Lights and sound update for the Hornby Network Rail New Measurement Train Class 43 HST Power car and Trailer Car Plus Conversion of 5 Hornby Mk3 coaches to NMT vehicles.




The Network Rail New Measurement Train HST power car pack was a bargain impulse buy from the Monk Bar Model Shop in York. Adding sound and updating the lights on the power cars was only the start!!!  The real work was to convert 5 East Midland Trains Mark 3 coaches to represent the Network Rail Mark 3 conversions used in the real New Measurement Train. The train has retained its original livery despite the addition of top marker lights on the power cars. Network Rail staff man the track recording and Pantograph coaches (with working VDUs in the former). Red and green (LED) Lasers scan the track and white flood lights provide illumination for the camera systems monitoring both track and overhead lines and, Oh yes! we have a driver in the lead power car!

With the mammoth size of the "how it was done" web pages, I've separated these from this summary page, with access via the links below for those interested in the detail. (The links are also repeated at the bottom of this summary).
