Ok, United and lockey buses

I really want to make some vintage buses. Ok, United and Lockeys would be perfect.
I'm no expert on buses, but if anyone knows where I can get dimensions or maybe a profile drawing to get me started that would be great.
Cheers

textured building

Large building at the top of Grey St.

Here is my work in progress image of the large building at the top of Grey St which over looked the track side water tower.
This is the first of a selection of buildings that were on the far side of platform 4.
I will play about with a few elements before I texture it so they are the correct proportions. Once done I will put together to put in my route.

regards

Derek
