Rapido Trains UK is proud to announce that they will be adding the next batch of BR 1Co-Co1 ‘Peaks’ to their range of N Gauge ready-to-run models. In much the same way as the locos were produced in real-life, the development of our N Gauge Class 46 has progressed as a continuation from the Class 44 and Class 45.

With the success of the first Type 4 diesels, Derby Works began the development of the next generation of even more powerful locomotives, the Class 45 and Class 46. These would go on to form the bulk of the Midland mainline fleet for many years.

The 45s and 46s were not named after mountains as their Class 44 counterparts had been, though whilst many were honoured with the names of famed British Army Regiments, they still retained the nickname ‘Peaks’.

The first BR Class 45 entered service in late 1960, with the class soon becoming the main loco to work out of St Pancras on the Midland mainline services, demoting the dwindling number of steam locos to cover local services or freight.

The final variant of the ‘Peak’ began production in 1961, now with Brush Electrical Equipment fitted after re-tendering for the next batch of locomotives. This tweaked ‘Peak’ would be known as the BR Class 46.

Externally it looked almost identical, as it had the same engine and body, however its electrical equipment had received an upgraded generator and different traction motors. Developed by the Brush Company of Loughborough, these upgrades replaced the previously used Crompton-Parkinson electrical equipment of the Class 44 and 45.

In total, 56 Class 46 locomotives were produced, with the last being built in 1963.

The 46s were used for varied work, being seen on NE-SW cross-country services, long distance freights from the West Country and some Trans-Pennine services. With Class 45s and 46s often being seen working trains to destinations across the South West and alongside the trainspotting location of Dawlish, it’s no wonder the loco has a soft spot in many diesel enthusiasts’ hearts. The last Class 46 was withdrawn in 1984. Prior to retirement, the class did have one final claim to fame. Class 46 No.46009 was acquired by the BR Research Department to be used in an upcoming crash test. This famous and very public experiment would see BR test, under crash conditions, the integrity of its supposedly impenetrable Nuclear Flasks.

Seven different Class 46 locomotives are being produced with the following specification:

• Directional lighting
• Next18 decoder socket
• High-quality motor and drive mechanism for smooth running
• DCC sound option
• NEM coupler pockets
• Separately-fitted wipers
• Etched radiator fan grill
