ANother win for the good guys. Thanks, Age of Steam Roundhouse!

Today, my "google alert" for Age of Steam showed me this link from the crane company that loaded the 643 onto the flatcars. They have a few pictures and the information about the cranes that were used. Interesting information for those of you who load rail equipment.

Thank you Jim Evans for the posted link.

For those that are interested: based on the lift information in the link, the depressed flat car carrying the boiler (90 ton) had a gross weight of just under 200 tons with an average axle loading of just under 25 tons per axle (suspect some axles may have had more load given the boiler was on one end of the car more than the other).

This was well below the load limits of the KRL 152 depressed flat car although the distribution of weight may have been a consideration.

Sidenote: to replace that leading axle on the flat car (as mentioned by others earlier in the thread) they had to use at least two 50 ton jacks? (maybe less since the trucks didn't need to be lifted)



The frame and wheel base were reported in the link at about a 160 ton lift. The load limit of KRL 127007 is ~247 tons with a light weight of ~83 tons. But with a load weight of 160 tons the total gross weight was ~243 tons or about 20 tons per axle (12 axles on the flat car).

Overall, it would seem if the loads were fairly well distributed that the load per axle was well below 37 tons/axle. Not sure if the railroads insisted on that for their track or if it was just the way things worked out.
