I've often shared videos of me "chasing" trains, usually me racing the train to various spots in my car. A little over a year ago, I chased a train between grade crossings on low-speed industrial trackage by literally running after it. This would be a first for me.
The context: When many railfans go looking for the Minnesota Commercial, they often find the Hugo or Findlay turns, which run between their namesake Minneapolis exurbs and allow for more frequent photo opportunities. This is also because while RR employees are friendly, they discourage folks poking around their shop area. I had arrived in Minneapolis that afternoon from Chicago, with the intent of chasing the Hugo the next day. I picked my hotel because of its proximity to the Commercial's roundhouse, so I wandered over to see what I could find.
I encountered a 34 job returning from the yard with a pair of tank cars to be dropped at the Minnesota Recycling Association. I theorize that one of the yard crews normally handles this switch, hence why it does not appear on YouTube as often; it occurs at an irregular time. While I regret not having my real camera with me on this walk, I'm glad I at least got something, as the next day I'd break a car window chasing the Hugo before I could get much footage.
