It is very common for the string to bind where it passes though the side of the building. As the toy is used, the string will acutally wear a little slot into the edge of the hole it passes through. It does not take much for the binding to start.
The best fix is to find a little brass eyelet that will just slip tightly into the hole. You will need to disconnect and re-string the 445 to install it. Put it in from the outside, so the rolled edge of the eyelet is on that side. Don't try to roll the inslde of the eyelet It will be fine just the way it is.
I wish I had a part number for you. If I have a moment, I'll take a look and see if I can figure it out.
The Doctor is In ! I see you have a minor problem, permit me to assist. The eyelet is part# 259E-18 That should help your problem. I am also repairing a 445 tower, I have to get a few parts. Any good parts supplier should be of help to you on this.
Till My Next Missive, I Remain The Humble Yet Strangly Evil Doctor!!!!
According to my favorite parts dealer's listing, 259E-18 is the eyelet that goes in the the lever.
I checked the Lionel Service manual, and it is indeed the correct part number for the eyelet that can be inserrted into the side of the building.
