Part 2:

Buildings set in place 

Gluing in the fillers to bring grade crossing pieces to correct height. The small pieces between the rails are .030 styrene and the more rectangular pieces are .060 thick x 1/4" wide shown by the green pencil, but any width would work as long as the space allows it. 

Air brushed with Polly Scale "Oily Black" yes I still have some 

Now for the center stripe.

Step #1: Putting down the tape for the center of the road striping. This is 1/16" wide Fine Line tape used in the auto body shops. It is super thin and if put on the correct way it will not let paint bleed under and leaves a very sharp & crisp line when removed. 

Step #2: Applying the two pieces of 1/4" Fine Line tape to get the outside of the center stripe. 

I use the rounded end of a 6" steel ruler to press the tape down REALLY tight and this step is important, so as not to get any bleeding of the paint under the tape 

OK now pull the 1/16" tape up, leaving the center area ready to paint. I also used the 1/16" tape on the rail heads 

Now tape off the rest of the area to prevent over spray. Again I use the Green Frog Tape to prevent bleeding under. When praying the paint used three or four very light coats less is more in this case. 

What it should look like after all the tape and paper is removed 

This is what I use for the templates 

This is the Fine Line tape. I get it from "Painter Supply" stores in my area, but any good full service body shop supplier should have it
