Historical Background

The Class 66, built by EMD as the JT42CWR, became one of the most successful diesel freight locomotives across Europe from the late 1990s onward. Its reliability, efficiency and cross-border capability led to widespread adoption by private freight operators, particularly following rail privatisation.

Unlike earlier state-owned locomotive classes, the Class 66 symbolises the shift toward modern, competitive rail freight operations. Special liveries and promotional designs are common, with exhibition models like this Intermodellbau edition celebrating the ongoing popularity of both the prototype and the model railway hobby itself.
