Marvellous achievement James, well planned and executed. I was quite pleased to see you have chosen almost exactly the same control systems as I have - Lenz command station, LDT sensors, even down to the same Maplin power supply! Main difference is I use Rocrail instead of iTrains. I think you can do the same sort of things with both, but iTrains is much more "professional" in terms of the user interface.
As you say there is a LOT of preparation and wiring involved, but like you I find it is worth it. In your video it is all through trains and that is relatively easy to automate once you have the blocks and sensors defined. Have you ever attempted to run trains into the bay platforms or any kind of shunting? I'm sure it is possible but I never really got it to work consistently, so I tended to use railcars or similar push/pull trains so no uncoupling or run-around was required. Any thoughts?
I love your servo controlled signals, very authentic. I can see you sitting glass in hand in one of those patio chairs watching the trains go by and hoping your son hasn't figured out how to reschedule your services while you weren't looking!
Thanks for sharing the video.
Hi Dave,
Great to hear that you have a similar setup. I did look at RocRail when I started, but in the end went with iTrain because the UI seemed quite intuitive. I'm pretty sure they do the same things though.
The video did just have through trains, but I also have a railcar and an auto trailer. Those do travel between the bay platforms as well as round the loops. Goods trains also occasionally visit the bay platforms - shunting (travelling in reverse) to get in or out, but I'm using hook and chain couplings so for me, although the software could do it, automating coupling and uncoupling isn't possible. The railcar and auto trailers routes are influenced by which platforms they find available, they generally prefer the bay platform and from there will shuttle back to the other bay, but if the bay platform is occupied then they will go to a different platform and consequently follow a different route. So we get quite excited when the railcar visits the front loop which is quite a rare occurrence (little things!). I've worked on the routes to keep running interesting, varied and free flowing. I'd like to add a small single track goods yard some time which will add further interest I hope. The thing that makes the running most interesting of all though is that so little of the layout is visible from any one place!
I've been using the LDT sensors for a long time and always found that although they work well they are very sensitive (1mA triggers them), so it wasn't taking much rain to have them triggering false occupancy - really annoying! Last year I discovered a simple hack for this using a resistor to basically leak a bit of current around the sensor and thus reduce it's sensitivity, they are now triggering at I think closer to 10mA and I'm only getting false occupancy in serious rain now which is just fine!
Currently my son is content to sit at the computer and pretend that he's running the trains, but he's just figuring out that you can change the points by clicking on them, so it really won't be long before he's 'improving' the programming, presumably followed fairly shortly by actually improving the programming - that's when I shall sit comfortably with the glass of wine you mention!
