Iv'e gone with LMS upper quadrant signals after taking Dave's advice. These should now match the BR period depicted. Instead of rushing these, I should have researched Semaphore signals properly - alas, that's how we learn!
A class 31/4 waits on signal.
A HST speeds past the junction on the main line. This is a much beloved Lima set and it's great to see it run around and around.
An old, detailed Lima 50 pulls an old Hornby class 86. The 'Freightliner' flats are the old Hornby type. I think they look much better with a bit of custom weathering.
Just for a comparison - a new Hornby 50 pulls a new Hornby Class 87. The difference in detailing is remarkable compared with the older varients.
I've added a bit more flock detailing to the front of the brambles and also painted the distant forrest atop the rear hill a lighter shade of green. A few telegraph poles have also been added.
