JWRStation Posted February 15, 2016 Share Posted February 15, 2016 I am having problems with using the double header facility with my Eurostar's. I have two of the 2013 models both with the same basic Hornby decoders and one of then configured to operate in 'Reverse'. On the track and seperately controlled they move at the same relative speed throughout the scale HOWEVER, as soon as I 'double head' them the 'rear' unit hardly moves until after about 70mph speed setting but at cruise of 150mph they both run at exactly the same speed. Additionally when I try a stop from cruise one of them will not actually shut down and tries to keep moving... In fact if I lift it off and even with all controls at zero put it back on the track, it keeps moving; I have to power down the system to get everything to reset.At the moment I am running the unit with seperate controls just remembering to keep the speeds synchronised and it operates smoothly...Joe Link to comment Share on other sites More sharing options...
JWRStation Posted February 15, 2016 Author Share Posted February 15, 2016 Additional info. I have run both Euro's on seperate tracks and this problem still occurs however, when I double head two of my TTS loco's, Gadwell and King Richard II, they both run at the same speed throughout the speed range despite being two different motor gearing configurations.Joe Link to comment Share on other sites More sharing options...
Chrissaf Posted February 15, 2016 Share Posted February 15, 2016 On the track and separately controlled they move at the same relative speed throughout the scale..Plan B,What about trying this, not an ideal solution but may be a suitable work around. Give both Eurostars the same DCC loco address. Then see if they behave in a synchronised fashion from a single controller, that is not configured as a 'double header'.

Howbi Posted February 15, 2016 Share Posted February 15, 2016 @JWR..........you could also check that both decoders CV's are identical, ie CV3 & CV4 and it could also be beneficial to set CV29 to '2' for the normal direction loco and '3' for the reversed direction loco to remove DC running.

Fishmanoz Posted February 15, 2016 Share Posted February 15, 2016 I would also try emailing HRMS from the Help window in RM and see if they have any advice. Link to comment Share on other sites More sharing options...
WilliamDavid Posted February 15, 2016 Share Posted February 15, 2016 Has anybody managed to use double headers successfully? Link to comment Share on other sites More sharing options...
96RAF Posted February 16, 2016 Share Posted February 16, 2016 Yes, although I had to fiddle with my 0-4-0s to balance them. Any other loco combo seems ok although with 2 X TTS you have to have the same start delay set which precludes rescueing a failed steamer with a deisel or vice-versa.

JWRStation Posted February 17, 2016 Author Share Posted February 17, 2016 OK. Coded both to the same number but with one operating in reverse and then track tested with both on the same track but slightly apart. Both ran round together at all speeds so a result... Slight difference in acceleration so dropped the settings to 20 to even things out and gives a much better look to setting off anyway. So, for a permanently linked identical couple (enphasis though on identical) double coding works better than double heading....Thanks ChissafJoe Link to comment Share on other sites More sharing options...
96RAF Posted February 17, 2016 Share Posted February 17, 2016 @jwrIts still worth flagging the original snag back to HRMS even though you have got a decent workaround. Link to comment Share on other sites More sharing options...
