No no no...! I mean if my refrigerator car had real journal boxes they'd have been smoking last night...This is a real kookie ocurrence :... While cleaning crud off car wheel treads last night and checking gauges of, this one reefer I have coasts Ok in one direction but binds up in other direction...I checked everything I could with NMRA track guage tool and even added labelle oil in journals..It's now on the RIP track and was probably reason I was getting slipping on grades...Blessing in disguise though as it got me to clear out all poor rolling cars ( til I buy state of the art trucks or just start a collection of all new rolling stock )...Anyone know how this binding ( hot box ) happens in one direction only ?? !!
