The girder rail came from
the Port Authority (Pittsburgh's) old
Overbrook line. It
had only been in service for about 12 or 13 years
and was hence lightly worn.
Moreover, it is still sufficiently ductile
to be rebent to other radii.
PTM arranged to have it rebent to the
required radius for this
loop by another rail transit agency. The loop radius was specifically
designed so that someday we'll be able to run two-car trains of Red Arrow
centerdoor and St. Louis cars, e.g. cars 66+73 and 14+24 .
The tongue switches seen in the current attachment came from the Port Authority
