Having taken the plunge into DCC but without the benefit of much info from the makers of the Select controller I have learnt the hard way just what does or does not do what!
When I got the first loco to move on a test track it was like the launch of the Queen Mary (1936 version). When the first coder died after a few minutes it was time to question my actions/installation. Eventually calming down and accepting that two out of three was not bad -- after all it was a system which could be used by anyone over3 years old and some of our readers little darlings were wiz kids 5 minutes into the game.
I tried a double header -- that produced a red flashing light which doubled up as a navigation beacon! Only solution =96 pull out the mains plug.
Constructing more than a straight line demanded some testing as we progressed. Having read that Peco insul frog were fine for DCC without special treatment at the =93frog=94 exits I proceeded to lay my initial back to back pair of three way points with a double slip on one of the turn out sides.
Energising the track with croc clips produced no immediate problems BUT! As soon as the loco encountered a mucky piece of track the controller flicked through 11 back to 03 and the loco casually rolled off the end of the track having regained contact and now not being under command!
This should have rung warning bells but as cleaning cured that problem let us carry on. This involved more ambitious power application to two adjacent tracks and passage through the point matrix. At this point it became evident that the wide wheels of my brand new 1982 Hornby class 25 could bridge all of the long turnouts at the frogs. In go the insulating connectors on everything except the double slip =96 on measuring, that had sufficient insulation not to be affected -- WRONG!
Not wishing to lift all the so well installed track to fit the same to this unit I hit upon the idea of painting the frog point rail surface with lacquer( just sufficient to keep the wheel from its little bridging efforts. This is very successful. There is nothing on the printed page or website to indicate just what may happen when transient shorts occur ( apart from the remark applicable to full blown short circuits tripping the overload. So far the little excursions caused by transitory short circuits have run the test train off the track only about 20 times and until I had cured each problem required a constant watch on the controller to catch each drop out in time to do something.
Now that the initial installation has reached almost 5 metres run I am beginning to wonder just how much wiring is going to be saved!
