When we were rebuilding the the ex Reading 2100 in St.Thomas ON we were talking to Timken and we were looking at a price of 150,000 to 200,000 to change over to roller bearings. On the subject of friction bearings on cars there was alot of maintenance involved with the up keep of friction bearings. Some railways still use cars that have Friction bearings but they can use it only on there own lines. These type of bearings are prone to give you hot box problems because of lack of oil,and could cause a derailment. So the AAR and the #1's decided to get rid of plain bearing wheels. Also the railways saved alot of money from the parts they did not have to have on hand and saved bigger bucks on the staff they could lay off who oiled and repaired these cars.
