@@xxMRBUNDYxx Thanks for the comment. There are some notes in the comments below and I hope to do a video over this winter.

There are three drive motors, one for before the lock, one in the lock and one after the lock. Each motor drives a 6mm toothed belt that runs in a u shaped channel 20mm wide and deep. The teeth are upwards in the channel and mesh with teeth on a carriage that is about 50mm long and runs in the channel on top of the belt. The carriage contains a powerful magnet. The boat has a complimentary magnet. Each belt goes round a pulley at each end and through the motor drive mounted below the u channel. The carriage is long enough to bridge the gap between the different drive belt sections. Between each section is a vertical guide. The pulley block for each fixed section is attached to this guide but the pulley block for the lock section is free to slide up and down in the guide. So the lock section runs up and down on sliders at each end of the lock section. The lock section is mounted on two M12 bolts fitted vertically underneath. These bolts run through two nuts each mounted in 3cm gears in a gearbox with three such gears in a line, the centre gear is turned by another motor. Limit switches stop the lock top and bottom. Two more three gear gearboxes drive the opening and closing gates with micro switch limiters. As each action is controlled by micro switches or magnetic detectors, the completion of one action triggers the next action in sequence. Simple DC electrics, no electronics required. There are also turntables at each end to turn the boat round, so it goes backwards and forwards. The whole system runs on 12v DC so the drive to the 6mm belts and the lock motor and the gate motors are reversed just by reversing the polarity as the boat is turned around by the turntables. The same sequence is then run in reverse. Took a lot of experimenting to get it right. All gears, gearboxes, pulleys, motor mounts etc were 3D printed using a small Monoprice printer. There are three drive motors, two gate motors, one lock motor and two turntable motors all geared 12v DC motors running at between 2 and 6 rpm. Happy to share FreeCAD files. Hope that helps.

So glad that you liked it. Great fun to have a working lock on the layout with the boat going back and forward, turning at each end with a turntable under a hill at each end.

A fiddle yard is designed as a number of tracks where you can store trains ready to go out on to the layout when needed. That way if you want to run a number of different trains you don’t have to take them off the rails and put them back on again. You just pull the train out of the fiddle yard and, when you have finished using it, put it back into the fiddle yard. The trick is to get as many tracks in a small space as I don’t have much space.

Hi. There is a brief explanation as a reply to a comment below. Thinking of doing a “how to” over next winter.

@@robinsundt8826. Yes, I had read that, and I'm glad to say that it gave me the broad strokes of the nature of the mechanism as it were, but should you film a more detailed video on the topic whenever you find it convenient, I would be most grateful. Thank you for replying to my comment so promptly, especially considering the age of this upload, and I wish you all the best. Kindest regards, and stay safe.

I second this request. As a brand new viewer, I have no idea but I think that we can take it as read that when you say that you're going to make a "how to" video, joining up the number of teasers that you've produced so far, for the undoubted delight of every one of us lucky to have found you, you mean it. More power to your elbow, sir!

The water is 1/8th Perspex painted underneath. Below is a 15x15mm plastic “U” channel. A 6mm toothed belt with the teeth upwards runs in the channel. A 50mm long carrier, with matching teeth on the bottom, runs in the channel and has a magnet in the top that picks up the magnet in the boat. There are three separate sections of belt each with their own motor, one above the lock, one for the lock and one below the lock. This way the lock can go up and down separate from either end. Pulleys at the end of each section turn the belt and the carrier can move from one section to the next across the small gap.

@@robinsundt8826 Thank you. That is nice system.

If you go to DCCconceptsforum.com - Modelers Workbench - Signals and signalling, there is a write-up including the circuit diagram.

HI, The LM-ID modules are made by DCC Concepts, check the website DCCConcepts.com. They have dealers everywhere and they ship worldwide.

@@robinsundt8826 Hi Robin, Thank you very much for your reply, much appreciated. I better get planning and building!

The station is a Metcalfe card kit. Excellent and easy to make in any shape you need.

@@robinsundt8826 thank you

Because!

The original video, that I posted 3 weeks ago, has had 35,000 views. This is an update that I only posted today. See more by searching for my name.

@@robinsundt8826 any chance of a full layout tour ?

Check out “Hayling Branch Line Start” for the first part of the layout.

No

There is a “making of” video on my channel if that helps.
