Hi
Finally finished one tunnel portal. This is how I did it, it's not perfect, maybe I should have started on a straight.
What you'll need
- 1.5 x 1.5mm styrene angle Evergreen 291
- 0.5mm thick styrene
- Anko Modelling Paste

I cut 13.5 to 14mm wide styrene strips (measure between the rails), then length depends on your tunnel.Being on a curve,
I cut kerves into the styrene every 10mm to 15mmso I could bend it around the curve and glued it between the rails using Gorilla Clear glue.
I then glued the 1.5x1.5mm angle to the styrene using push pins as a spacer or 1.5mm balsa. This became the trough for the modelling paste.
Mask the top of the 1.5x1.5 angle so to keep the modelling paste out of the inside of the rail and the outside of rail, apply the modelling paste, I used paint scraper to level it off.

For the area between the rail and the tunnel, I placed an 8mm high plastic strip so that I have something to guide the paint scrapper against the rail and the strip. Mask of the inner part of the rail.

The modelling paste will crack if applied too thick, but I just filled these in as the modelling paste dried off.
Tip remove the masking tape 24hrs after you have applied the modelling paste otherwise it lifts ups and turns to cr#p.
You can sand the modelling paste fill required, well depending how good you leveled it to begin with.
Then paint I used Vallejo Model Colour Deck Tan for the concrete that was the closest for me.

Hopefully I didn't miss anything.
