Few locomotives have captured the imagination quite like British Rail’s English Electric Type 5/class 55 ‘Deltics’. First introduced in 1961, their twin Napier Deltic engines generated 3,300 horsepower, making them the most powerful single unit diesel locomotives yet produced at that time. Capable of speeds in excess of 100 miles per hour, the Deltics were worthy successors to the famous express steam locomotives of Gresley, Peppercorn and Thompson on BR’s East Coast Main Line, working top link services such as the Flying Scotsman, the Talisman and the Aberdonian. The arrival of the HST in the 1970s displaced the Deltics from their old stamping ground, but the locomotives found further use on cross-country routes. A special return working from King’s Cross to Edinburgh on January 2nd, 1982 heralded the end for the Deltics in service, but with six locomotives preserved and operating on mainline railtours and heritage railways, the legend lives on. Different starting processes can be selected with F1: 1x press button = warm start / press button 2x = false start / press button 3x = cold start
F2 slows down the locomotive slowly.
F5 enables the heavy load mode: The diesel notch is always one up compared with normal operation. If you want to jump two notches, simply set CV 104 to 150 (instead of 130).
F8 turns on the manual ntoching. Once F8 is on, you can use F7 to notch up and F6 to notch down. F8, F6, and F7 must be turned off to return to normal mode. If F8 is off and you press F7, the prime mover will run to full speed.
F14, F18 and CV 170 value 0 or 1, can switch between a "normal announcement" or an announcement "with gong".
F9 can increase the speed of the spirax valve by double-clicking it. The speed levels are slow, medium and fast.
17 will bring the locomotive to full stop.
F21 and CV 168 = value 0 or 1, can switch between a "normal" or a "squeaking" wiper.
F28 and CV 164 = Value 0, 1, 2 or 3, can switch between different rail joints (three coupler can be activated with CV 165 = value 1).
F29 and CV 169 = value 0 or 1, can switch between the "Automatic Warning System (AWS)" or the "Train Protection and Warning System (TPWS)".
