The brand label was changed to Great Model Railways (GMR) in 1979, although the Airfix name was still included. However, Airfix left the model railway business in 1981. The models were sold to one of its main competitors Palitoy which produced the Mainline range of products. The former Airfix moulds together with the Palitoy-designed 2P 4-4-0 and Class 56 diesel were later re-sold to Dapol Ltd and then subsequently to Hornby. Dapol provided new chassis for the 14xx and Castle. The remainder of the Mainline Railways had been produced for Palitoy by Kader Industries and ownership of those tools remained with Kader, is later used to form the basis of the Bachmann Branchline models. Dapol continues to produce (but not promote) most of the kits but as the moulds (some now over forty years old) wear out the kits are being discontinued. Hornby continues to make 4 mm/ft scale models from the Airfix mouldings.
