I thought of this on the train this morning as we rolled through Summit. What's the reason that the "siding" closest to the new parking garage in Summit is on an incline while the rest of the track is level with everything else? This track is where they normally store some catenary maintenance cars. The only thought I could come up with was perhaps there used to be some kind of building there that received freight a long time ago before a parking lot was put there.
