Hi Spurr
The signals BR are available from the DLS. I've just downloaded them into T:ANE and already have them installed in TS12. Don't know why they don't show up for you.
Bloodnoks signals require targets placing on the tracks at junctions behind the signal, both for colour light and semaphore types which use bloodnoks script. Have a look at the built in ECML route at the southern end to see how the targets are used.
The colour light signals will display either theater boxes for numbers and letters or direction feathers if feather targets are used. You place the target behind the signal, a straight one on the mainline and a left or right direction one on the branch line or crossover. Once the signal and targets are placed, click on the question mark and then on the signal and a dialogue box should open. You can name the signal or leave the default name in place and click on the tick to close the dialogue box. Open the dialogue box again and click on the text "Update". This will cause the signal to display its name and should also cause a feather or theater box to appear on top of the signal.
Note that the feather or theater box will only appear if the signal can "see" the next signal or buffer stop behind the target along the line. It may be necessary to toggle the junctions to allow the signal to "see" the next one.
