Western Speedo Drive(s)
Hello. Just detailing my JLTRT Western, modeled as first running, now can anyone confirm
that when first running the Western's had speedo drives on both bogies( I believe they did.)
plus on the same axle opposite side there was what I understand to be the mileage
recorder. Were mileage drives on each axle too.

I cannot find photographs of Western's in early years (up to about 1970) showing the 3rd
axle without a speedo drive. David Birt's book the Class 52 Westerns, on the inside cover
there is a good photograph of Western Glory, showing both speedo and mileage drives, on
the 3rd axle of each bogie. Pages 71-72 show both sides of Western Pathfinder later in its
life with speedo drive on each bogie .
Any information would be appreciated. Chris

Chris,

The only axle end "additions" that you need are these:-

"A" bogie - Inner axle, driver's side - Smiths speedometer.

"B" bogie - Inner axle, driver's side - Smiths mileage recorder.
"B" bogie - Inner axle, secondman's side - ATC earthing brush.

The speedometer has only ever been at "A" end, and the mileage recorder only at "B" end.
The centre and outer axles of each bogie did not have any devices attached to them.

Roger - thanks for the reply. I didn't even know about the ATC earthing brush. Presumably, this uses the same four holes for mounting on the axle as the speedo drive. I have sorted out some photos to see if I can identify this brush, whereas the speedo and mileage "boxes" are round, is the earthing brush rectangular.
Many thanks Chris

Chris,

The ATC earth brush uses the same four holes at the axle end that are used by the speedo. The mileage recorder is rectangular at 1:1 scale. See Phill Dyson's "Warship Details" thread:- http://www.westernthunder.co.uk/index.php?threads/warship-details.15/

Post #16 shows the speedo equipment at "A" end on D821. Post #18 shows the mileage recorder at "B" end of D811.

See Mark Smith's excellent close up pictures below of the ATC earth brush on D832.

Alcazar, Daifly,

The "little handle" is the earth cable crimp. The ribbed umbilical connecting the earth brush to the bogie frame is there to prevent the earth brush from rotating with the wheel.

Surely the cable runs inside the ribbed bit, and contacts the wheel centre at one end and the loco frames/bogie frames at the other?

I'd have guessed the ribbing was a steel flexible conduit for protection?

See the Bradford Barton book "The Westerns", page 29. This shows "B" end, secondman's side of a Western.
The earth cable can be clearly seen tied to the outside of the flexible hose and then disappearing up into the loco's
body.

What I termed a "ribbed umbilical" is actually a bit of hose with steel reinforcement.
