[quote user="CMStPnP"]I believe that is true for TexRail. DMU's cannot operate in conjunction with scheduled freight trains. The DMU's have a specific window of operation if I am not mistaken and after that, they are not allowed to run.......unless I read it wrong long ago.[/quote] You didn't read it wrong. But the first waiver expired and DCTA asked for a new one. FRA granted this new waiver without the condition of separated freight and passenger traffic on May 31, 2012: <a href="https://www.regulations.gov/contentStreamer?documentId=FRA-2010-0180-0019&attachmentNumber=1&contentType=pdf">https://www.regulations.gov/contentStreamer?documentId=FRA-2010-0180-0019&attachmentNumber=1&contentType=pdf</a> The complete FRA docket is here: <a href="https://www.regulations.gov/docket?D=FRA-2010-0180">https://www.regulations.gov/docket?D=FRA-2010-0180</a> Here is technical crashworthiness information of the Stadler Flirt: <a href="https://www.regulations.gov/contentStreamer?documentId=FRA-2010-0180-0006&attachmentNumber=1&contentType=pdf">https://www.regulations.gov/contentStreamer?documentId=FRA-2010-0180-0006&attachmentNumber=1&contentType=pdf</a> The Stadler Flirts are allowed in mixed traffic on TexRail. If lines with predominant freight traffic and higher than 80 mph passenger train speed might get waivers remains to be seen. Technically there is nothing to be said against it. [quote user="CMStPnP"]. However, I personally would never ride a Talgo on the BNSF Freight Line in the NW. Nor would I have ridden the trainset if the purchase went through for Wisconsin. [/quote] That is interesting as the Talgo 8 is FRA Tier 1 crashworthiness compliant: <a>[url]https://www.fra.dot.gov/Elib/Document/2125[/url]</a> But even if it were European standard I wouldn't see a reason not to use it. I don't remember how often I have posted the following link. It would be helpfull if someone would read it[:)]: [url]https://www.fra.dot.gov/Elib/Document/2125[/url] They analyzed crash scenarios of five differently crashworthiness equipped trains always against a train with a conventional locomotive leading. On page 3 is Table 1 showing calculated fatalities at a closing speed of 30 mph. Higher speeds and higher masses will change the numbers but not the tendency. But everybody does what he is comfortable with. Regards, Volker
