Hello Helmut,

I like the inset rails across the brick pavior path - on a curve too !. Very neat.
No crossing barriers/warning lights though ?.

Regards,                 Michael

@Michael
There will be a warning sign later on - for unaware freerailers, of course.

@all
4QD's controller arrived just in time ( Dec 5th ) as a nice Santa Claus present ( In Germany, S.C. will either leave presents in shoes put out in the evening or appear in person on the eve of  Dec 6th ) for me. It was put in and I was able ( after some negotiations with my son ) to drive up and down the hill without any sweat. That GBP 251,50 were well spent, indeed! Loads were rather hefty- 200kgs on a 'lowry', thanks to the built-in regenerative brake it held set speed downhill, no runaway nor need for a mech brake. Fellas, that's what I call "fit for the job"

Sunday we visited one of the now ubiquitous "Xmas-Marketplaces" they set up everywhere. This one was particularly nice as a 5" gauge oval with a real steam loco to pull the kids around, was set up. Watching this for some moments, my wife asked: "What would it be if we had one on our line?" Now, Michael, if that materializes, whistle and bell plus exhaust would please the neighbours all day, if necessary. As their clothesline is close to the tracks, the washing would also pick up a nice aroma...:glad:

Amazing, love what you have done so far! glad: I had the option to buy a 15-inch gauge mining locomotive with a truck engine and chain drive, a few years ago. I have about 1/5 acres on the property and the majority of that is totally flat and devoid of trees. I seriously contemplated building something like this but with wider track for a short while.
That is, until my wife made it clear that I'd have to do the work on the RR as I could afford each piece and that I'd also have to sell my WW2 Jeep and a great deal of my WW2 collection as well.
Needless to say, I passed on that offer. That would have been a 20-30 project before any trains would have run, the way my wife was describing it and I'm not even remotely that patient.

Wow, it's right alongside a sidewalk and street? You are going to have people and cars stopped to watch the train from time to time once it's running! :2t:

Hi all,
not that you think I've been lazy during the past months. The bridge deck has been covered entirely with planking, and the plans for the run into the garage-cum-shed have been finalized.  As I did not want to cut grooves into the yard's pavement, I pondered over the possible ways to have the rails fastened to it. Here's what I came up with:

OK, here's the progress so far before the rain came down today.

Hi all,
I have another issue that IMHO is very important when operating in such a dimension. In the smaller scales over here, you get away without compensating the chassis of a two-axle vehicle, as the flange depth will provide sufficient vertical play ( in case you don't overdo it ) to keep the effects of the unavoidable sags and humps in your track at bay. But the great outdoors is a different kettle of fish altogether. At a flange depth of 5/16" ( The standard for 10.25" gauge ) any axle distance of more than 16" on a rigid chassis will give you trouble,when the car is running light. Were it loaded, it would keep the track better.
For testing a way of semi-compensation, I made up a wooden frame vehicle with the axles spaced 24" apart. This is , taking into consideration wheel diameter ( 5"), gauge ( 9 7/16...9 5/8") and minimum radius ( 14' 9" ) the widest reasonably applicable distance.
Just for kicks I tried a rigid chassis first and I sent it light down the hill into the curve at the foot. It jumped the rails halfway in the bend. Nice crash indeed.
I did not want to use springs, so I came across rubber dampers. I had shelved some of these anyway, so I put them under one axle of the contraption.
See attached pictures:


here' the underside, the elastic mount is on the right-hand side:


And finally the mounting of the dampers:



Doing the same test again, it really hugged the rails and sped round the bend you can see in my previous post. I ha dnot then taken the garbage cans away, and it bumped right into them. Yours truly decided to go for a ride himself, precariously clinging to that narrow board and daring only to start from half the hill.  Speedy enough it was, and no harms were reported in the end.
