mike, 
One of the little joys of #Wikipedia is the pedantry in some of the entries.
For example, about the song Chattannogo Choo Choo:
The train is described as departing from Track 29 in Pennsylvania Station. At the time, the facility only had 21 tracks.
"You leave the Pennsylvania station 'bout a quarter to four", but The Birmingham Special departed at 12:30 p.m.
