Meanwhile in St. Louis.....
While Randy wrestled with grids all day, this is what I contended with down in St. Louis at the Museum of Transportation. Note, the pole isn't supposed to be like that, nor is the catcher supposed to be on the ground.

No lives lost, just a minor annoyance. At lest we have a small enough operation, it was easy to just turn the power off, get on top of the car and turn the pole around and install a new rope. Also, the shop is close.
I have seen much worse. You could have bent the pole or broken a pulloff. I couldn't tell if the car has a trolley wheel or a shoe from the photo. If it has a shoe, I would suggest changing to a wheel. Wheels work better when backpoling.
The last time I operated the 4391, many years ago, I managed to bend the pole up pretty good on a backup move. It took about half a day with the help of Ed Woytula to fix it. So I decided not to run any single-ended cars if I can avoid it. Let better men than myself handle these problems!
As for the 4391, it is now a Bulletin that your conductor has to walk beside the car, with extra rope pulled out of the catcher in hand, to prevent a pole-bending event.
One of the real secrets to making a backup move with a pole is to have the wire properly hung and tensioned. Hard to do that effectively for all the wire we have in the air, and that usually means the webbing of overhead going into Barns is the last to get attention.
Yes, wheels help, but using them in a mix with carbon insert sliders introduces other issues. Some interurbans used a backup shoe design that had a toggle action to cause it flip over when backing to minimize 'incidents'.
Art,

ReplyDeleteIt has a wheel, which is correct for the car's PTC paint.
ReplyDeleteThe wheel works 99.9999% of the time backing up, just this once something didn't work right.
Art, your e-mail bounced back. What is it again?
