About Derails

[Jim Holland]

Greetings!

	Yes!  Thanks for that information!

	The 1946 and 1949 ERA maps of Pittsburgh show a multitude of derails. 
Yes, the derail symbol is in the legend and it possible that such an
item could be a cartographers mistake  AND  it is possible that the
derails on the map are an all-time listing while most were not current. 
One shows on Shiloh before the turn onto Grandview OB on the 40-Line but
member Bob Dietrich lived close to the area and he has no recollection
of such.

	The 49 shows at least 2, possibly 3-derails which would have to be
powered back to original position by an outbound car.

	48-Arlington shows two derails outbound as trailing switches, spring
returned.

	Also another trailing-spring-returned derail is shows at SHJ OB just
after the 38-39-40-42 lines split from the interurban.  Seems it would
make more sense to have one before the split so all would be protected
from a rollback into the tunnel.

	Don't have time to scour the map for the others at this point nor to
look for the email where I sent the listing I had found.
