Hi, I have a Hornby mixed freight set (I believe it's a R1236) with two locomotives and the select controller. I have added lots of track, points, locos, etc, and it is on a layout up in the loft. Recently, with the instruction book in my hand, I tried to 'consist' the two locos using #10 to control them, this worked fine. Then I tried to 'consist' a Flying Scotsman railroad and a Mallard railroad on #11 on the select unit. Nothing happened! Now all my locos have 'lost' their codes and the select controller's led flashes when I put any load on it. However, the sound units on Mallard and FS seem to still be working. Is there anything I can do at home to fix the flashing led screen? Thanks in advance
