Chilled Cast Iron wheels were still being made in the 1950's, but were going out of fashion.<br /><br />"White says in 1930 it was estimated 95% of freight and 25% as passenger car wheels were cast iron. According to the 1940 Car Builders Cyclopedia the freight car percentage was down to 82%. The AAR began to ban cast iron wheels in the 1950s and they were completely gone by 1968. However, it is not impossible to find them on unused cars transferred to maintenance of way service." http://www.vbfamily.com/Wheeldoc.htm<br /><br />The actual date of the AAR ban of Chilled Cast Iron wheels on new & rebuilts was 1958. The interchange ban came years later. <br /><br />Bottom line... it depends! (which plant, etc)<br />Also see http://utahrails.net/industries/griffin-wheel.phpJakehttps://www.blogger.com/profile/00660496053397412430noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-37921602743475459152016-12-24T08:33:13.644-08:002016-12-24T08:33:13.644-08:00I have a few questions since I am planning to incl...I have a few questions since I am planning to include a Griffin Wheel Works plant on my layout. How was the foundry sand shipped in the early 1950's? In gons/hoppers or in LO's? I'm also confused as to whether the wheels were iron or steel in this era. If making new wheels, would one be melting pigs of iron, or would one receive steel in some form from a nearby steel mill? Griffin had an "electric furnace".<br /><br />Thanks!<br /><br />-JeffJeff Aleyhttps://www.blogger.com/profile/18261260319825210952noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-40815435311975704092016-08-04T20:13:27.379-07:002016-08-04T20:13:27.379-07:00Wonderfully informative post, Tony.Wonderfully informative post, Tony.arbe1948https://www.blogger.com/profile/07200787740351997164noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-36747853338324231092016-08-03T18:09:07.435-07:002016-08-03T18:09:07.435-07:00 Good post!

It's quite interesting reading about these little known aspects of maintenance. The fellow rolling a balanced, 800 lb. wheel is amazing!<br /><br />-Jack Shall<br />http://blog.lacentralrr.com/Anonymousnoreply@blogger.com
