HR2937S FS, 6-axle electric locomotive E.636 3rd series, isabella livery, without gutters, ep. V, with DCC sound decoder

The electric locomotives E636 of 3rd series (units from 276 to 469) represent the last evolution of the popular E636 group, that introduced the articulated locomotive architecture already in 1940.

Built until 1962, they are recognizable at first sight for the vertical rib on the cabin (same as 2nd series units) and for the horizontal rib on the chassis (same as 1st series unit), but they have also several other technical evolutions realized during the more than 20-years long construction, such as new transmission system with rubber pads and full disc wheels and more reliable electrical and mechanical devices.

With their top speed of 110 km/h they were used mostly for freight services, but it was possible to see them pulling also local passenger trains, and they were spread over almost all the electrified Italian lines.

Same as most of the other groups, also the E636 received several modifications over the years that partially modified their aspect, between them the removal of the front cabin gutters in the ’80s years and the livery simplification in full light brown “Isabella” starting from 1990.

GENERAL TECHNICAL FEATURES OF THE MODELS

-        NEW MOULDS for the bodyshells, with accurate reproduction of all the typical details of 3^rd series units in the state of the ‘80s-‘90s years, with modified front gutters, bodyshell ribs, steps and handrails coherent with the period

-        New wheels with accurate reproduction of the typical transmission system of 3rd series units, with full disc wheel centre and rubber pads

-        Reliable mechanics with articulated chassis and gearboxes in metal, powerful 5-poles motor in central position with double cardan shaft transmission to the two head bogies, two wheels with traction tyre

-        New electric system with NEM 660/21MTC decoder plug for DCC and DCC Sound decoders, predispositions for rounded 23 mm speaker or for a rectangular “sugar cube” speaker 11x15 mm

-        “S” items with sound decoder ESU Loksound V5 and speaker installed by factory, with specific sounds

-        White front lights and rear red light with automatic inversion according to the running direction and possibility to disable them independently, either in analog (through DIP SWITCH on main PCB) and in digital (through decoder functions)

-        Possibility to install a central pick-up skid for running on 3-rails systems, with commutation through jumpers on main PCB

-        NEM 362 coupler pocket with short-coupling mechanism on both heads, with possibility to disassemble the coupler pocket to complete the fronts with all the realistic details

-        Accurate reproduction of the pantographs Type 42LR FS, full in metal and with pick-up possibility; closed position extremely flat and realistic

-        Many separate parts in metal or plastic for maximum accuracy of the reproduction, with photo-etched lamps support on the buffer beams

-        Length over buffers: 211 m
