RhB (Rhaetian Railroad) class ABe 8/12 3-part electric powered rail car train. The first of 15 units ordered so far and developed for the RhB by Stadler Rail was delivered in October of 2009. The continuous power output of this powered rail car is almost as high as the class GE 4/4 III, the most powerful RhB locomotive.
The unit with road number 3502 set a speed record for meter gauge railroading in December of 2010 in the Vereina Tunnel with a speed of 145 km/h / 91 mph. This train will be the premier powered rail car on the RhB for the future. It runs on the famous Bernina line or on the Arosa line among other routes. It's a normal sight to see a larger number of freight or passenger cars coupled to it.
The LGB model of the "Allegra" is completely new tooling. Both powered end cars have Bühler motors for more pulling power. Naturally, additional cars can be coupled to it just like in the prototype. The model has a correct arrangement of LED headlights that change over with the direction of travel. Of course, the doors can be opened. The model has a DCC connector, two general-purpose electrical sockets, traction tires, sprung buffers, snow plows, and a multi-position selector switch for the mode of operation. All of the cars in the train have metal wheels and are close coupled. The model has many separately applied details such as rear view mirrors, windshield wipers, antennas, brake hoses, etc. The model has reproductions of the engineer's cab areas and interior details; both cabs are lighted. It also has a prototypical paint scheme and lettering. Length over the buffers approximately 206 cm / 81-1/8".
The interface connector on the 20220 is a new development with the following pin assignments: 1 0 (Gleis/track) 2 0 (Gleis/track) 3 B (Gleis/track) 4 B (Gleis/track) 5 Motor 1 6 V+ 7 V+ 8 GND 9 Motor 2 10 TAKT 11 MR 12 LS+ 13 LS- 14 MV 15 ZBCLK 16 V+ 17 AUX 6 18 Input 1 19 AUX 5 20 AUX 4 21 Input 2 22 AUX 3 21 AUX 2 24 AUX 1 25 Index 26 L0v 27 L0r 28 ZBDAT Several functions must be controlled using a Susi connection.
