CN 176-16 is a Woodings Railcar track motor car.
Notice that the rear wheels are not painted black like the front. The original factory installed pressed steel wheels have been changed out for ‘ice cutter’ wheels on the rear driving axle. Look close and you can see gap between the wheel tread and the rail, and the ice cutting ring around the entire centre of the tread. These ice cutter wheels also had a larger flange to compensate for the ice cutter ring.
Now that was totally amazing. I never had the slightest inkling that there was studded tires for Railcars. Thanks very much for that Paul, very much appreciated. Also, I left you a note, after all this time, on the Edmonton Aux. train post from awhile back.
A little more information on ice cutter wheels for track motor cars … The rear brake shoes also had to be changed out for shoes that were slotted to accept the ice cutter ring, thereby allowing the brake shoe to make wheel contact.
I was noticing what you mentioned above. The brake shoes when you zoom in, would have to be narrower to accommodate the raised cutter. You can also see when zoomed in, that the rear wheel sits higher on the rail head because of the ring. There is a noticeable gap at the bottom of the wheel.
That’s interesting Paul I’d never heard about those either. It reminds me of the rubber “traction tires” that used to be on model trains.
