And you do it so well.

Done that for 5 railroads, '40s, '50s and '60s.

Nope. For the example I cited, I have the ETT,
The TT Special instructions, and the TT Special
Rules, which was a separate publication.

Congratulations (seriously). I'll see your 40 and
raise you 48 1/2, all in Ops and Mechanical.

I don't think so, but being an ASMA Member, it wouldn't
be that difficult to do.

Besides, I never claimed the problem didn't exist.
Obviously it did. I do challenge the thought that
blanket speed policies for a specific territory or
locomotive type were based on the possibility that
a certain kind of wheel or other hardware was in the
train somewhere or not.

To say that a specific type or series of locomotive
had a maximum speed allowed solely on the basis of
what might be in the train is stretching it too far.
The publications cited above have plenty of specific
car maximum speeds, either by car type or by numbeer
series or sometimes both.

BUT, there had to be some way of doing that, did there
not?

The ban on interchange cars is not in question, although
I do wonder how and why WP would accept such cars in
interchange decades after the ban went into effect.

Never questioned that or claimed otherwise, now did I?

Seems to be plenty of that to go around.
