If you look at the pre-1951 rule book, the yard will only extend to the far switch of the station affected by the yard limit sign.


'It make sense if limits extended from East Revelstoke up Eagle pass to the west switch of Three Valley.' No, I disagree with this statement.

From what I understand from the old-timers this was not the case UNLESS IT
WAS SPECIFIED IN THE ETT FOOTNOTES.
My understanding is that in 1948, the Yard Limit at Taft (for example) extended from the Yard Limit Board west of Taft to the
east switch at Taft and no further.

Put it this way, similar one-direction only yard limits were in place on KV territory and I know for fact yard limits did not extend between stations
as Chuck speculates. There were cases where they did, but I reiterate, in those instances, the ETT footnotes for the affected subdivision
clearly stated those instances.

After the new UCOR took effect in 1951, a number of provisions changed, such as the designation of 'passing track.' Yard limits no longer carried the
direction-specific provisions in the ETT either.

I can't give a complete answer, but yard limits were defined in the field by yard limit signs. Yard limits only applied within the limits defined by those signs. The timetable indicates stations where "yard limits" exist but the crews have to be familiar with the actual physical limits so their train is under appropriate control as they approach the sign. In most situations that would probably be not much more than a train length beyond the outer switch at each station.

I can't confirm whether or not the position of the letter in the ETT has your proposed meaning, although it does seem logical.

A long while ago this note was posted:

This raises a question in how the letters were used. Pacific region TT
(http://www.cptracks.ca/data/TimeTables_Employee/ETT_92_1948_Sep26.pdf)

It shows the following for the Shuswap Sub (I've only included the yard limit letters):

Revelstoke Z
Clanwilliam
Z Three Valley
Taft Z
Craigellachie Z
Malakwa
Cambie
Solsqua
Z Sicamous Z
Annis
Mowitch
Canoe Z
Salmon Arm Z
etc.

I assume that a letter on the left side of a station name denotes limits on the west side of a station and letters on the right side designate limits on the east. I'm also assuming that if a letter is missing the yard limit extends to the next station.

But if true there many problems. Sicamous works well with the station entirely within yard limits but what about Revelstoke? It make sense if limits extended from East Revelstoke up Eagle pass to the west switch of Three Valley. Or maybe the limits extend from west switch Three Valley to east switch Taft?

Does anyone know how the limit letters are paired up to form a west-east interval?

Thanks
