Bachmann have since released a new version of the "Deltic", in both the OO gauge "Branchline" range and their N gauge "Graham Farish" range. Bachmann have also produced the "Deltic Prototype" in OO gauge (previously only available as a plastic kit from either Kitmaster or Dapol), however this had been commissioned by Locomotion Models - the model railways arm of the Nation Railway Museum - and was not generally available in model shops. A "Graham Farish" N gauge model is available, as a stand-alone model, and as part of the "Merseyside Express" train set.
