I decided to revisit this scene previously shot during the day for a little look-see. Anyway I can't help but wonder if there is a better angle on this. We'll see when it's warm enough to do so. Brzzzz... Gotta get back to the car. I'm starting to know why they call this the Windy City. One would think that a native Ohioian would be somewhat use to this kind of weather by now. NOT!
Mike Pianta's solution for motorising the double crossover got me thinking:

The problem with his solution is that it's lineair; to get from 'both straight' to 'both branching' you would have to slide the length of the key. So I thought, there must be a rotary way to do the same thing. Today I finally got around to playing with this idea and this is what I've got. It's not complete, I haven't done anything about RCX control, but the concept works.
The curved slopes are what's pushing the actual points, rotating the axle is what moves the contraption through its 4 states.
As pictured both sliders are pulled in by the elastic bands, so both points are straight. Turning the axle 90 degrees either way makes the dark grey cams push one of the sliders out to make that side branch. Turning the axle 180 degrees from its current position makes the light grey cams push both sliders out together.
For RCX control I'm thinking knob-wheel + touch sensor or rotation sensor to make the motor turn the axle 90 degrees at a time but I'm not sure how to initialise it...
My landscape and track sections use a combination of MILS and PennLug with the track 2 bricks above the baseplate. Annoyingly that's one plate too low to run the axle below the points to control both halves at the same time...

Leaving the Victorville narrows behind this UP stack train has run wrong line to overtake the stopped oil tank train and is now negotiating the crossover to regain the normal track to reach the flyover at Frost and continue via a descent of Cajon Pass to access the LA basin.

If you see yourself in this or any of my other pictures, let me know in the comments, or by emailing me at loser: [at] istolethe [dot] tv.
After some more fiddling I managed to get it work with 1x2 Technic beams and half beams (never liked the name 'liftarm') as cams instead of the dedicated cam part. The big advantage is that it's a plate lower, so now I can run the axle below the track to the other end of the crossover. Next test is how much a long axle will twist...
As a result of a blockage on the line near Culgaith (a hay bale that had rolled onto the line and hit by a previous northbound service), the 10:49 Northern Rail service from Leeds to Carlisle on Wednesday 21st August 2013 was terminated at Garsdale. Under the watchful eye of the Garsdale signalman, who had clipped the points, the driver of the two class 158 units slowly negotiates the crossover to gain access to the up platform. This unit then formed the 13:03 to Leeds and the hapless passengers were advised to detrain at Skipton and travel to Carlisle via the 'Little North Western' route and to change at Lancaster onto a Virgin Trains service. With the abolition of Garsdale box in about five years time I wonder what contingencies will remain in place for such eventualities and who will be available on location to supervise such a move. I rather think that under the regional control centres, movements like this may be a thing of the past and operational flexibilty will be reduced.
