    Railcar undercarriage.

    Yes I can agree with Garrett M. But I wonder why are what appear to be a part of the suspention so hot….Friction perhaps or is this an electric style train such as a subway or commuter train and this is part of the third rail pickup???..I don’t think so may be another clue will help.

  • Eric Krause

    The hot spots appear to be compressive stabilizing/dampening pads in the suspension system where the “work”/force applied to them translates into heat/thermal energy and being less thermally conductive than (or thermally isolated from) the surrounding metal components results in a build-up/temperature differential of the heat/thermal energy. There may also be some degree of difference due to varying materials with different emissivity and reflectivity than the surrounding components.

    I think that the hot spots are brake pads.
