This model - 56105 Colas

  • Colas livery with ‘Diamond’ style logos
  • Era: 2020 - Present day
  • Distinctive fabricated cab shape 
  • Cutaway buffer beam 
  • Diamond mesh side grilles, cantrail grilles and roof grille
  • Steel cab and cab side window frames
  • Additional air conditioning vent on the second man’s side


  • 21 pin DCC interface and innovative removable panel to allow for easy DCC chip installation and access to the comprehensive dip switch control for DC users, which allows access to all of the DCC functions for lighting, without the need to remove the model from the track.
  • Photo etched grilles throughout the model including body side, roof and cantrail.
  • A wealth of separately fitted parts across the model, including bogies which aren’t just one piece mouldings to allow for proper detail relief as well as the under frame.
  • Full independently controlled lighting, allowing for parked, yard, light engine, and ‘on train’ modes, with realistic levels of brightness and colour representative of the prototype being modelled. Prototypical day/night lighting configurations for the modern livery examples.
  • Realistically bright (or dim depending how you look at it) cab lighting, driver’s desk with individually printed dials and decorated full depth cab interior as per the prototype.
  • Hall sensors for fully adjustable automated flange squeal on sound fitted models. This feature automatically provides the characteristic screech as the wheels enter sharp curves. Not having to activate the sound manually only adds to the immersive effect whilst driving the locomotive.
  • Power bank providing smooth uninterrupted running, which combined with floating centre axles, allows trouble free road holding and power.
  • 5 pole motor with twin flywheel and low ratio gearbox for prototypical running speeds typical of the class.
  • Provision to order drop in wheelsets to easily convert the loco to EM and P4 gauges for those modellers that wish to showcase the unparalleled levels of detail and accuracy of the model with equally accurate trackwork.
  • Highly detailed and accurate underframe with numerous separately fitted parts.
  • Individual details and finish that has been rigorously researched and applied to each model to represent the individual prototype as accurately as possible.
  • DCC sound with custom ESU project for our factory fitted sound version and stay alive fitted to all models. ESU Speaker in the chassis as standard for a balanced combination of low and high frequency sounds to accurately reproduce the prototype via a custom recorded sound project.
  • Etched name plates as appropriate to each model number.
  • Locomotive specific details across four series of locomotive builds.
  • Both standard and revised cantrail grill options depending on prototype.
