Vacuum Braking (7) Implementation (1)

Nearly a year and a half ago, I designed the vacuum braking system for Sentinel 7109. Now it's time to start putting it together.

The design has evolved slightly.
Ball-style Isolating and driver's Valves and no gauge isolation valve
The actual topography of the pipe joints and links may not turn out quite like the diagram but it won't be of any consequence (he said confidently!).

Most interesting is how it will look when assembled.
This is only the beginning!
I'll put as much as possible together for a better photo before assembling it on 7109. It gets a lot worse than the above picture but I had to grab a quick camera opportunity before my wife found my enhancements to the kitchen floor!

It's a good practice to pre-assemble all the bits before installation to ensure all the connections are present and correct. There's very little room to move about in the cab and it's 25 miles away if bits are forgotten!
