scruffulous Posted January 28, 2019 Posted January 28, 2019 This is the narrow gauge train layout I presented at Brickvention 2019, based on the idea I developed for OcTRAINber 2018 (i.e. using a hidden subsystem of L-gauge train "carriers" connected to the visible narrow gauge trains above via magnets). Totternhoe - Brickvention 2019 by Mike Pianta, on Flickr You can see it in action in this video: Totternhoe by Mike Pianta, on Flickr While the layout worked well enough to give me encouragement to continue to refine it, there were a number of issues that meant, at first, I couldn't reliably run most of my locos. The green simplex is a loco with the cab removed to reduce weight. This was the most reliable loco I had because it was light. I had to rebuild the yellow diesel to reduce the weight, and it ended up being fairly reliable. I did get the base (i.e. no cab) of a steam loco (not shown) round the loop, but ran out of time at the convention to fully test it with the cab. I think I can get it there, though. So, lots of issues, and dealing with them meant that I didn't have time to detail the layout as much as I would have liked - I think it looks a bit plain. I'm hooked, though - I love the challenge, and the cuteness of the narrow gauge trains is irresistible. Quote
XGBC Posted January 28, 2019 Posted January 28, 2019 nice narrow gauge railway you have. i have some ideas on how to improve it like inventing a system to couple your wagons together or you could use stronger neodynium magnets. hope this helps XGBC Quote
Hod Carrier Posted January 28, 2019 Posted January 28, 2019 I thought this was amazing last year and I still do now. It’s such a clever idea which has been so well executed, and it looks fantastic too. I can only see it improving and getting ever better as you add more detail. What’s the issue with loco weight? Are they breaking away from their magnets when running light (e.g. on their own without a train)? Is there any way to either increase the strength of the magnets or maybe making baseplates thinner so that the magnets can run closer together? Quote
ProvenceTristram Posted January 28, 2019 Posted January 28, 2019 (edited) Oh, this is just superb. Your trackwork is inspirational (3w is such a better idea for a truly small railroad at this scale). I would love to see your take on a few shunting steamers for this line. If you're inclined to share, I'd love to take a look at the LDD those ore carts - they're amazing.

I actually deliberately haven't coupled the wagons together - one advantage of not coupling them is that I can decouple the hidden carriers below without my hand interrupting the view from above. It's not as straight forward as using stronger magnets. I'm already using pretty strong ones, and if I go stronger the attraction/repulsion between magnets on the carriers causes the carriers to tip over (even when weighted). 7 hours ago, Hod Carrier said: What’s the issue with loco weight?

Yeah, if the loco/wagon is too heavy, or the track is too uneven, the carriers (below) separate from their rolling stock (above). A thinner base does help (my OcTRAINber prototype, which was straight track, had a thinner base), but I need the current thickness to build the points and other tricky track geometry. 5 hours ago, ProvenceTristram said: I would love to see your take on a few shunting steamers for this line.

LEGO Train 12 Volts Posted January 28, 2019 Posted January 28, 2019 This is an amazing idea for a lovely result! Quote
Jawaguy4 Posted January 29, 2019 Posted January 29, 2019 Saw this at Brickvention this year. Really impressive and fun! Quote

Can't upload the LDraw file here, but there aren't that many parts, so you should be able to figure it out from this exploded image.

Man with a hat Posted January 30, 2019 Posted January 30, 2019 Yes, the concept was already brilliant. But it is really great to see it in a layout, which also looks really nice. And quite clever how you did the points/switches. Quote
raised Posted January 30, 2019 Posted January 30, 2019 Amazing. Its really cool to see how a your entry in OcTRAINber ended up being a complete layout for Brickvention. Are you planning to integrate it into the MLTC layout, just like was done with the Puffing Billy layout? Quote
Laura Beinbrech Posted January 30, 2019 Posted January 30, 2019 Really lovely narrow-gauge railway you built there, and the method you came up with for "motorizing" such small locomotives is quite clever, too! I gotta say, that 3-stud rail placement seems to be just about perfect for simulating 2-foot gauge in LEGO, and your tilt skips look almost exactly like pictures of such wagons on the Leighton Buzzard Light Railway that I've seen on the internet.

I'd booked this layout idea into Brickvention way ahead of OcTRAINber, but it took me a long time to realise that I could use a test-build as an entry for that competition. Actually, I'm not sure I would have been able to present a working layout if I hadn't done that - OcTRAINber allowed me to iron out some of the technical issues. Puffing Billy was integrated into the VRLGM Victorian Railways layout, which was appropriate. This layout, which is based on narrow gauge railways in the heart of England, would be out of place there, so will most likely stay as stand-alone (but will hopefully improve in quality and size). 3 hours ago, Laura Takayama said: Really lovely narrow-gauge railway you built there, and the method you came up with for "motorizing" such small locomotives is quite clever, too!

Thanks. I feel the same way about the gauge. I really struggled to get the dimensions right for the tilt skips. The ones I built for OcTRAINber were all wrong, but I think they're pretty close now.

zephyr1934 Posted January 31, 2019 Posted January 31, 2019 That's brilliant and beautiful! Even before anything moves the layout looks great. Then knowing all that is going on behind the curtain... you are insane and I am in awe. A little spooky to see the cars following along behind the engine without a coupler in sight. Quote

It's OK we're a great support group... We completely support your MADNESS! LMAO This is even better than before. I showed your original to a lug member and we both want to integrate it into the clubs layout. Any pictures of the "support system" would be welcomed! I bet the kids love seeing floating cars lol how many look under the table! Quote
M_slug357 Posted February 7, 2019 Posted February 7, 2019 @scruffulous This is pretty sane tbh... I thought I was losing it when I started working on a 9V track powered narrow gauge system... lol I had to take a break, but may go back to it...? Quote

I'll do you one better with a video demonstration: NG: 9V shunter (vid 1) by Nick Jackson, on Flickr The two main problems were traction and electrical contact. If I had more time & know-how...!
