Guest dawdawes Posted January 16, 2016 Share Posted January 16, 2016 Hi all, I am looking at building an RhB exhibition layout using the Kato and other 9mm equipment. I want to incorporate both AC for the main and DC for the branch as I love the ABe4/4 and want a Pirata model. I visited St Moritz but can remember the point they changed over and if it was fully isolated or on a dead track, now we have the Allegra it makes life interesting. Any advice would be welcome.

RMweb Gold PaulRhB Posted January 16, 2016 RMweb Gold Share Posted January 16, 2016 Pontresina is the changeover point for AC and DC. The Allegras can just swap voltage and carry on but the other trains require either a change of motive power for the Bernina Express or passengers to change trains. There are some tracks that have switchable catenary. I assume there's some sort of indicator that conforms to the driver which power is on as they approach but I don't know the exact method.

Guest dawdawes Posted January 16, 2016 Share Posted January 16, 2016 Thanks chaps, need to look at pictures to see how the changeover is wired, I do like to get the detail right Link to post Share on other sites More sharing options...
Guest dawdawes Posted January 17, 2016 Share Posted January 17, 2016 Ok so Pontrasina, do the Allegras drop pans on way in over the dead section,then re raise with the 2 dc pans, then visa versa on way into the AC and put up the 1 AC pan? Link to post Share on other sites More sharing options...
