The resources section is a "WIP" If I ever get the time to get stuck back into it, it will be cleaned up into something more readable for the gibberish sections
Welcome to the site!
Why not go 16x16 on the layout A 16 foot drop / climb will give you the space to put the bottom level around a foot or a little more below the top layer, while still ensuring most of your stock will manage the climb
I think the phrase 'chalk and cheese' would be an apt description of the difference.
The Lima sports a classic noisy pancake on one bogie with iirc two axles driven. Iirc there are pickups on four wheels?
The new model sports A 5 Pole Double Flywheel Motor Driving 4 Axles with All Wheel Pick Up
While not as good a puller as the 071 the new 201 is an entirely smoother beast than its Lima relative.
