Classic Trains Magazine is running a profile on the 2-10-4 or Texas type
locomotive.

Our own CPR Selkirks T-1-a with the same wheel arrangements were renamed
after the area they worked.
--Not true. They were never renamed, they were Selkirks right from the
start.
Who built the first T-1-as (5900 to 5910) Was it Lima or MLW.
--CPR never bought any locomotives from Lima except the Shays. All of the
Selkirk's were built by MLW. (Except the 8000, that is a different story).
5912 to 5917 are different.
--In what way? 5900-5919 are all part of the same order.
What size were the drivers on the T-1-a?
Any idea what their top speed was?
Classic trains suggests that the "Texas 63 inch drivers were too small for
the weight causing imbalance thus were limited to drag freight speed"
--Not necessarily. This depends upon the design and many other factors, one
of which would be how well the drivers were balanced. One of the problems
with big ten drivered locomotives was the piston thrust. Locomotives with
cast one piece engine beds were much better than those with fabricated
frames. In the mountains, where the Selkirks ran, power was more important
than speed.
Some of the T-1-as had their number board on the running board midship
where I have a photo of 5912 with no number plate amidship and the number
under the window. why was it so?
--As built they did not have running board valances. These were added later.
Were the early Selkirks boilers grey as well. Some of the B&W photos I
have seem to show a lighter shade on the boiler and Darker on the smoke
box.
--No. They repainted the smokeboxes more often than the boiler jacket, and
what you think is grey is probably a fine layer of road grime, plus
variances in how the film of the day saw different colors and shades of
colors. Only the T1b's and T1c's were painted in the maroon and gray colors.
