Bachmann, was purchased by Kader Industries in 1987. Kader had previously produced models for Palitoy under the 'Mainline' brand. Palitoy required its manufacturers to produce and retain ownership of the toolings and Kader had used the toolings and added new ones for models commissioned by Replica Railways following the demise of Mainline.
Kader formed Bachmann Industries Europe in 1989 with their main UK headquarters in Moat Way, Barwell, and the following year launched the Bachmann Branch-Line range for the British market with the moulds that had previously been used for Mainline and Replica. From this starting point Bachmann has developed the range further and now produce a large range of models competing in particular with Hornby.
In 2000 Bachmann Branch-Line bought Graham Farish, an N gauge manufacturer, and since then many of their models have been made available in both gauges.
