Well, perhaps not a different time (mine are circa 1999) but they do have ALL the street crossings and it is indicated if they are underpass (UG), at grade (no indication), or overpass (OP).  Rivers and other items like signal towers, setout sidings, businesses, block names, and signal tower ID's are included.  Makes it much easier to name all the signal towers on a route.
Between the schematics you cite and the ones I have, a complete set can be had.
Send me an email and I'll zip them up for you.
