Not sure as yet as my gardens on a bit of a slope. inItial thoughts are to run a double track length along a small retaining wall at the edge of the patio about 25 foot in length. There is a small gap in the wall for the pathway up the garden about the middle, possible removable bow string bridge to connect both sections of the wall. Also would like to model an industrial theme (quarry, mine or factory).
Early days so unsure and don’t want to bite off more than I can chew.
Thanks for the welcome
Slopes can be a challenge, but then so were they to the early railway builders - so I would suggest that aiming to get as close to level as possible is beneficial, by doing what they did; cuttings and embankments.
I've always tried to keep it simple, so on my first garden railway in Sussex, where there was a 2 ft drop down the garden, I started at the top in a very shallow cutting (just a few inches deep) and the rest of the line was built up on sleepers which, happily, formed an attractive visual edge to the shrub borders. I've tried to achieve something similar in a slightly flatter garden here in Norfolk, but have succumbed to some gentle gradients.
I think the best advice is to try not to limit yourself to tight radius curves if you can possibly avoid them - the rule of thumb is that LGB R3 or 8ft diameter is a good minimum but, although it's desirable, it's not always possible.
It's often quite good to throw track down, a bit quick and dirty, and run a few trains - it certainly tends to concentrate the mind on where you want to go.
