Don't Give Up!

A few more documents from Rockhill:

One thing is still true: Your trains are 100% safe.  IRM inspectors see to that!

Then we have a visitor handout from the same era, including a complete IRM roster, about 25 pieces.  Almost all of this equipment is still on the roster, and much of it has been restored to operation.  The NSCA had to give up, but IRM didn't!

Finally, a nice picture and a drawing of the South Shore 700-class, originally built for the NYC in 1930 and rebuilt by the South Shore in 1955-58.  

The physics teacher in me immediately latched onto the idea of a "max. radius", actually a maximum curvature.  25 degrees corresponds to a radius of about 230', which seems rather optimistic.  But unfortunately none of these were preserved, so we'll never know.
