[QUOTE="kevinatfms, post: 16017099, member: 39344"] WMATA specified that tapered wheel cut on the truing machines. Simmons Machine Tool is who manufactured the wheel truing machines told us that it wasnt industry standard? They thought it was odd but the WMATA superintendent who specified the machines say on the rail around the DC area it helps with wear and NVH. I would have thought the opposite, especially in curves when the wheel skips through a joint. They used to have cars come in with some pretty ratty looking wheel sets. Either way, this guy was saying they run a tremendous amount of miles on the tapered wheel with no issues. So far so good since we havent had any warranty replacements on the custom built bits. If i can find it, ill post up some pictures of the WTM's and the 500T press. They were seriously impressive machines. The ones they removed that were 20+ years old were refurbished and sent out to another municipality like 3 weeks after we removed them. I couldnt believe they would still be of use but SMT said they do it all the time. Cost for us per machine was $2.5million with a $635,000 credit per machine that went back to SMT. The in car A/C units were a pain from what i heard and they built a huge gantry/walkway system with 2.5t crane for those cars specifically. It was under another contract but the designer of our project did both so he showed us what was in store for each service shop. The whole unit basically unbolted from the top of the car and could be serviced or they could just swap in a new unit. Faster for them if there was a failure that required an extended removal period. Lessens the time the car is out of service and to WMATA that was everything. [/QUOTE]
