The title says it all but I can't work out if is is a circuit and how the condensate in the pipes is removed.

I am now thinking of the marshalling of freight trains. Would the shunters decide the order of the vehicles? From the point of view of having a fitted head of sufficient length, presumably the shunter would not marshal any vehicles having the 'wrong' braking system in the head even if through piped? How was it ensured that the right pipes were connected if vehicles were fitted and through piped? Did air and vacuum pipes have different connections? Regards, David

So were any goods vehicles that were not intended to run in passenger trains fitted with dual brakes? Regards, David

I was asking more about the period before nationalisation. I'm wondering about air braked passenger or freight stock going from for example LBSCR territory (air) to GWR territory (vacuum).

I'm thinking from 1850 to 1950.

When passenger or freight vehicles were worked into a different company's territory and those companies used different braking systems i.e. vacuum or air, what was the procedure? Did those vehicles have to be dual braked? Regards, David

Just a quick note to say that I started this topic and have been amazed at the scale of knowledge shown in the replies. Thanks folks, most illuminating. P.S. I didn't know that other companies also used symbols. Regards, David

When I had finished construction of the Parkside NBR van I painted it in the Precision NBR grey. However, when I put the wagon next to a GWR van painted in Precision's GWR freight grey you would be hard put to tell the difference. I guess any grey between light grey and dark grey would be prototypical!

Perhaps I'm being illiterate on this one, but what did the quatrefoil signify? On the crescent was the painting date inscribed on the crescent? I have looked at the link but am no wiser.

I recently completed building a Parkside o gauge North British van. Included in the transfers were a crescent moon and a quatrefoil. What did these symbols signify?
