OPB's analysis here of the rules and signal aspects is quite detailed and correct, but there's no "regular station stop(s)" for the Pere Marquette train between Union Station in Chicago and New Buffalo, MI, and there's nary a platform between 63rd st (the site where the train crossed over to the other track) and 52nd st (where the accident happened).
However, there certainly had to have been at least one intermediate signal between those two points, or someone has some explaining to do as to why the signals at the interlocked crossover displayed anything but a 'Stop' indication.
