I have managed to acquire a couple of P2K War Emergency hoppers. Sorry if I missed out on some info...working Prototype Rails dimenished both my limited brain power and my computer time. Has anyone taken the time to evaluate these things? I notice that the real CB&Q version lasted for some time...at least one still with wood sides as late as '71. I also notice that 398 of the ATSF cars were still in service in '53. Richard, I believe you noted that these cars received steel replacement sides in '58. Were the cars in original condition until then?
