Perhaps a better question might be "What precisely is the latest version/edition of the Amtrak Service Standards Manual?" Unless that is known, you don't know if the one you have is indeed the latest. But I have a sneaky suspicion the employee manual or any information about is held "close to the vest" based on what I read under the "Employees" section here: http://www.amtrak.com/about-amtrak I mean, after all, how would a lowly customer even dare to find out what an Amtrak employee is supposed to do. Of all the bloody cheek! Harrumph!!
