If you want more information on the M-497, look for the book titled "Flight of the M-497." It is co-written by the actual operator of the car, Don Wetzel, and is quite an interesting read.

According to the book, Mr. Wetzel was one of the last engineers to operate a steam train on the Central, and was selected because he was also an aircraft pilot who was familiar with jet engines. The run did occur on jointed rail.
While it is true the original poster asked a question about Budd EMUs, the op titled the thread the "fastest Budd car". The forum in question is "Self Propelled Railcars"
The modified DMU (RDC) at 183+ mph is almost 20 mph faster than Metroliners (EMU) at 165 mph and it is definitely a self propelled Budd car. I'm not aware if the non self propelled Budd built Metroliners rumor of 190 mph is true or not.
I went and read the book again, and Mr. Wetzel claimed that the M-497 actually did reach 190 mph, but was only recorded at 183 mph since it was deceleating through the speed points.
Seriously, read the book. I have an electronic copy.
