Update on my exploits for those that are not sick of hearing about it
I took the Magnum & trailer for test today, both failed. The annoying part is that a customer of ours (plant & hgv fitter) had promised twice to look it over for us & let us down. The result being that I took them both blind
Mag failed on:
No fog lights (should have checked them, I did every other light on it !)
No Blue line present (who’s gonna use it, but it’s fitted so must have a suzie)
One brake a bit low pressure.
Trailer:
One brake almost inoperative
Not a bad result for a 12 yr old truck & 20 yr old trailer
In the days of old when trucks were trucks, and men were men and sheep were scared!
A lot of trucks had a deadman brake as well as a trailer brake on the steering column, this eventually got amalgamated into the handbrake and would apply the trailer brakes and front wheel brakes. for emergency use really
This was connected by a blue line, which was like a red line with a bigger coupling. This auxillary brake line was phased out as trucks got more brake power, and extra bigger air resovoirs. Instead of making things simple, truck and trailer manufacturers started adding extra suzies, ABS, Fog Lights and Tail Lift cables

The blue line is as others have described above, I mentioned to the test guy that although it’s a '92 unit, I had driven lots of pre 90 vehicles with only 2 airlines But apparently it’s there & must perform it’s function (will have to check in case it’s been converted to 2 lines & just cut off
Good to see its nothing major Toyt, I do remember sometimes putting on a blue line, but I had no idea what it did.
As for a dead mans handle, we still have them in trucks over here. I think that is what they call a Johnson Brake here, stops the trailer dead in its tracks.
