Some years ago I had a layout constructed commercially for me. Due to various reasons it has been largely untouched for several years. When resurrecting it, I discovered a fault which I am sure did not occur before.
On a particular turnout (Electrofrog) a loco will happily traverse from the toe of the turnout onto the branch line without hesitation and return just as happily. However, when the turnout is set to straight ahead the loco will stop dead when the leading driver reaches the wing rail. When pushed on, it will pick up when the drivers clear the wing rail. The same scenario occurs on the return.
All the wiring is as configured by my supplier, who unfortunately has ceased trading, and all the steps usually carried out on Electrofrog turnouts have been done - Electrically connecting the stock rail and closure rail on each side. The power supply is wired here as part of this), Removing the 2 link wires beneath the rails, Connecting the Polarity Reversing wire under the frog.
I am at a complete loss to explain the cause of this problem, Please can anyone help?
(Apologies for the wordy question)
