Diesel locomotive H0, C77, 247 059 of ECR, Era VI, prototype condition around 2020, light gray, sound + smoke, DC/AC

The Class 66/77 is equipped with a load-dependent, pulsed smoke generator that produces varying intensities of smoke plumes according to the load. The built-in sensors, which provide situational sounds in curves, are controlled by a LokSound V5.0 M4 decoder. This "jack-of-all-trades" understands not only DCC with RailComPlus® but also the M4 protocol, allowing it to register itself with ESU ECoS or Märklin® central station. Since it also supports Motorola® or Selectrix®, there is nothing preventing the use of the ESU Class 66/77 on all common central stations.

The integrated PowerPack energy storage ensures that comfortable operation is possible even on dirty tracks. The unique two-stroke diesel sound is particularly differentiated by two speakers through the etched fan grille on the roof. A complete lighting system including cab lighting, driver's desk lighting, and shunting lights with warm white LEDs rounds off the technical equipment. All lighting effects present on the prototype can be represented, including the "warning blinkers" or two-light head signal commonly used in Belgium. The frame and body of the model are made of metal and, with a weight of about 590 g, provide a prototype-like tractive effort. All structural differences between the variants are taken into account in the ESU models. Thus, the ECR locomotive features air conditioning units on the roof, wind deflectors at the side windows, and rectangular buffers. As with the originals, the models also have different covers for the battery boxes.

The Class 66/77 is a hybrid model that allows safe operation on two- and three-rail tracks with a wheelset gauge of 14.1 mm. For two-rail operation, simply remove the center pickup using the included tool. Done.

Embedded in a metal frame is a five-pole precision motor with slotted winding and noise-optimized commutator – developed by ESU. This motor transmits its power, tamed by two thick flywheels, through a worm/gear drive to four of the six axles. LEDs in the bogies provide realistic flickering during the braking process.
