This last month I’ve mainly concentrated on the operational side of Kyle of Sutherland. When it next appears in public it must work smoothly, as well as be complete.
The layout can now be operated in two independent halves, and this allowed me to thoroughly test my three controllers together with my five locos. As a result, “Pictroller 193” now has a new Forwards/Backwards switch and, in combination with “Pictroller 192” and my original Pentroller, everything seems to work fine.
I still feel the operation of the Router is not sufficiently intuitive, so towards the end of the month I designed a new Router. Instead of a rotary switch for “Up” and another one for “Down” trains, the new version has a rotary switch to designate the active controller, and another switch for “Up/Down”. This involves adding further switches to the Fulgurex-operated loop point. Unless someone comes out with a reasonably priced 5P 6W rotary switch, I feel I’ve reached the limit on traditional wiring. And I’m not yet minded to move into the world of relays.
I also feel I should wire signal servo operation through point switches to emulate the interlocking on the prototype. It would be no bad thing to only pull off a signal if the point were set correctly.
And, by the by, I found that the problems with 57587’s tender were caused by not enough side play on the leading axle. Ho, hum!
