So today has been spent on alot of detail. Taking lots of thin balsa strips and neatening tunnel mouths and providing a bit more structural detail on abutments

(additional bridge abutment detail) 

(tunnel mouth neatened up ready for some 'concrete' paper

After a comment from another user here I spent a lot of time checking clearances with two types of wagon before sticking down the walls to the HM customs warehouse 

(an early train load of taxable goods - probably scotch whisky) heads into the customs warehouse siding to check clearances) 

It took about 4 attempts in shaving off plywood before the wagons would clear the walls!

Another small step on the ferry was to round off the stern to give the end of the ship a more boat like feel. 

(ferry stern cut and sanded down) 

I'm also looking at the lighting masts and have created some balsa wood bases for them. The first attempt got destroyed when I tried to drill some holes through them. A second attempt was more successful.
