Key Publishing launches limited-edition GBRf Class 47 47739 OO model

A run of just 300 models gives Cavalex’s GBRf-blue Class 47 47739 immediate collector appeal, and the appeal starts with the prototype. Key Publishing opened the limited-edition OO gauge pre-order on April 25, 2026, with delivery due in 2027, putting one of GB Railfreight’s best-known Class 47/7s into a highly restricted release that is aimed squarely at modern image buyers.

47739 is the sort of locomotive that sells on identity as much as livery. Built at Crewe Works as D1615 in 1964, it became 47035 in 1974 and 47594 after Electric Train Heat was fitted in 1983, before eventually emerging as 47739. The long paper trail matters here. It gives the model a back-story that stretches from BR Blue era survival through Rail Express Systems, EWS and Colas Railfreight, all the way to its GB Railfreight chapter.

That GB Railfreight connection is what pushes the model into must-have territory. In December 2017, GB Railfreight bought 47727, 47739 and 47749 from Colas Railfreight, and by March 2019 the company said 47739 and 47749 had been repainted by Arlington Fleet Services at Eastleigh and would be based at Leicester for rail-service stock moves. GB Railfreight also said the locomotives were fitted with onboard translator equipment and Dellner couplings for unit stock moves, making 47739 a very specific modern operations subject rather than a generic heritage repaint.

Key Publishing has set the release up as a collector-led proposition. The model is split between DCC-ready and DCC-sound-fitted versions, both part of the same 300-piece limit. The DCC-ready model is priced at £209.95 including the £30 non-refundable deposit, while the DCC-sound version comes in at £309.95 including the deposit. For many buyers, the clock starts now, not when the first review lands, because a run this small can disappear before the wider market has time to react.

The engineering pitch is equally important. Key Model World says the bodyshell will use brand-new Cavalex tooling, and Cavalex says the Class 47 project has been designed from scratch using original works drawings and surveys of multiple locomotives. The specification includes a 21-pin decoder socket, removable roof panel access, photo-etched roof grilles, separately fitted bogie details, motor-operated roof fans, full controlled lighting, cab lighting, a driver’s desk with printed dials, a power bank, floating centre axles, a coreless motor and twin flywheel drive. That combination matters because it signals a serious all-new platform, not a repaint dressed up as a special.

For modern-image collectors, 47739 is exactly the kind of limited-run Class 47 that sells on recognisability, operational relevance and scarcity at the same time. In a market where the strongest releases are the ones with a clear story and a tight production cap, this one has both.
