THe project advances nicely – step by step

Ever since the cab had been delivered to Fliegermuseum Altenrhein on 14. June 2022, work is in progress on this non-profit project as fast as our main jobs in aviation and engineering allow.

Head of engineering Christian Rohrer is busy to make all the mechanical, electrical and pneumatic controls, dials and switches of 1950s technology compatible with the digital environment of a PC and Trainsim running on it.

Simon Heinz has put all his vast knowledge in Facility Management into the cab to clean the locomotive thoroughly but gently, in order to preserve the patina, the smells and the signs of 57 years of hard work on the network of the Rhaetian Railways.

The following milestones could be achieved:

September 2022: The electromechanical safety features and protections of the original power controller could be bypassed. The power lever now works again as in the original locomotive.

Oktober 2022: The electrical signal of the sequence switches of the power lever could be read out and connected via a complex A/D gate to the digital environment of the PC. As of now it's possible to drive the Trainsim loco with the original power lever.

November 2022: A large part of the registers in the Trainsim software (where all the values like speed, acceleration, position of switches and so on are saved) could be identified and read out. Now it's possible to simulate the vacuum brake lever with an electronic sequence switch and to operate the vacuum train brake in trainsim with this hardware.

November 2022: A 1000W Dolby Surround sound system has been installed in the cab. This way, all the authentic sounds of systems which are not installed "live" on the cab anymore will be heard in a powerful and realistic way while operating the sim, like the high voltage sequence switch or the ventilators of the drive motors..

Dezember 2022: Our head of engineering and a friend of his were able to bring the original Hasler tachometer of the Ge 6/6 II to life without using the wheel hub pickup who originally transmitted the wheel RPM to the tachometer. For this task, they used the highly precise power source of the engineering company they both work for. Now the tachometer displays the Trainsim speed register perfectly well, even sounding his distinct, characteristic electromechanical sounds,

Still to do;

  • Outside Visual Display
  • Engineering and construction of real vacuum and air pressure systems to have the perfect feels and sounds when operating the train / loco brakes
  • Interface work for all further components, like wipers, whistle, compressor and vacuum pump switches, door control and so on
  • Wiring of all components with the A/D interface
  • Reinstallation of all components from the laboratory in to the cab
  • Mounting of a technics rack behind the cab, housing the compressor, vacuum pump and the PC

cab successfully cut off and transported to altenrhein

Today we could transfer loco 703 to Vögele Recycling in Chur, and could cut off the two cabs with the help of the highly motivated and professional team of Stocker Netzbau AG and Vögele Recycling. After a whopping 6hrs of hard work with cutting torch and flex cutter, Stocker's team loaded the two cabs onto their trailer, drove our cab II to Fliegermuseum Altenrhein, and then took cab I to its final destination, the simulator hall of our partner association DESM at Boltigen BE.

In this newsreel of Swiss National TV SRF "Schweiz Aktuell" (german only), today's work s nicely shown .

Loco 703 successfully transferred to chur

This monday, we could transfer our loco 703 from Landquart to Chur according schedule. Our train driver and engineering team member Riccardo Keller made the impossible possible, and together with the loco schedule department scheduled the slightly older locomotive Ge 4/4 I 605 "Silvretta" to pull our loco 703 to Chur. So "St. Moritz" was accompanied by a "sister of age" on her last run. Immediately after our arrival at the Chur depot, our team started to dismantle a few things and to prepare the loco for tomorrow's cutoff of the cabs.
