I received my first T set and 103 a year ago at Christmas and just started a dry run for a real layout today. Always made weekend layouts.
To prevent the cat from enjoying my T while I'm sleeping or at work (in between days off), I used foam board to build a 5 sided box that I can easily work in or cut the packaging tape to better access it. The box is mock up of an Ntrak module that will be made of wood and foam to fit into the hatchback and to enjoy at home.
It's a forced perspective scene really, with 1:160 bridges up top and a 1:450 below. It'll make you think you are flying at an altitude of about 180 feet to view the T world like that.
First challenge is the T tracks with inclines just right. The empty 120mm track tubes make great elevation supports.
