The effect looks really good, Pete.
Sorry to be picky because you have obviously put a lot of work into them but are the signal aspects in the correct order? (yellow, green, yellow, red from top to bottom) and the signal in one of your photos is also showing yellow and red at the same time which shouldn't happen.(or have you taken the photo in the split second that the red changed to single yellow?
)
I would also suggest that the signal controlling the exit from the bay platform should be much lower so as to be in the driver's line of sight.
