Just the job, Annie - I could manage that climb in and out! And I see my "real world" house bricks are in use again.
I've just uploaded the four-track base - which of course could be used for fewer tracks plus scenic additions. Identical to the first base but twice the width. Surprisingly, I had problems adjusting the textures.
Yes, I meant a model house based on a photo of a recent develpment near here - on a sports ground (disused). I know I made it because it had a car port and in the config I commented, "Provide your own car" and tested it - somewhere. But I've searched computer, hard drives and memory sticks and it's nowhere to be found. Nor is it on older versions of Trainz.
