Paul-
That brake valve is more like a 14EL than a 6SL on the TLT rendering. AFAIK, no
SW1200RS loco's used this type of brake valve.

Andrew,
I would think that maybe CP specified this louvre arrangement on the SW1200RS
to allow the block lettering of the maroon & grey paint scheme to be on a
smooth surface. The CP MLW RS-2's had a slightly modified louvre setup on
the long hood to accommodate the CP block lettering. Check some photos to
see the two different locations for the CN lettering on the hood of CN
SW1200RS units in the original green & yellow paint scheme. The letttering
is located on the smooth area of the hood in both variations.
Looking at the cab interior drawing from True Line, I see that they show the
unit with 6SL air brake. Some of the early CP units had this as delivered.
Most however had 26L air brake as delivered. I can't recall the exact numbers
off hand. Also, the electrical cabinet should be centered in the cab
beneath the two centre windows if I recall correctly.

The first CP 8100-series SW1200RS deliveries were in June 1958. By that
time CN had already received 99 SW1200RS units over six different orders. The
CP SW1200RSes all had low louvers on the hood doors, similar to CN 1204-1247
(delivered in 3 orders between March and September of 1956), but different
from CN 1248-1304 (delivered between November 1956 and May 1958), which had
one set of low louvers and 8 sets of high louvers.
I don't know why the CP version of the SW1200RS had the same louver pattern
as the earliest CN units, when their front headlight-number board housings
are like the later CN units. In any case, what this means is that there's no
point of commonality in these character-defining spotting features between
the CP SW1200RS and any of the CN versions. CP's units are unique to CP.
