As the massive Big Boy locomotive left St. Louis it made a stop Monday morning in the suburb of Kirkwood, a town big enough to have an Amtrak station. There was quite a crowd but I squeezed my way to the front, looking for a clear shot. The backlighting was terrible but this will do.
As the train pulled to a stop right in front of me it let go a mighty blast of its whistle. Ow! The sound meter on my phone said it was 113 db but I bet the reading would have been higher if the phone hadn't been tucked into a holster. Half a minute of that can cause ear damage according to some web page I found (so it must be true). I haven't experienced the like since maybe the last Led Zeppelin concert I attended.
