The building does still exist as a banquet hall type of place. I suppose this is the best one can hope for when many large stations are in total disrepair or demolished. On one hand, Amtrak cannot support the station when 4 (6 at best) trains come thru each day. The Bendix station is, size-wise, perfect for 4/day. Were one to get aggressive and route South Shore trains to SBUS, you're looking at maybe 10-12 trains/day, still barely enough to support such a grandiose structure.
The station is in the middle of the GTW/NS shared ROW, but is slightly east of the actual shared trackage. I still don't understand why, when the real estate is available, they don't just cross the two mains at one interlocking. If you look at the map linked below, you can see that there is plenty of width to the ROW for 6+ tracks (probably there at one time) and empty fields on either side.
For growing up in SB, you'd figure I would know a lot more about the west side, but I don't. They west side heyday ended when manufacturing left SB, and by the time I was old enough to get out and around, most of the rail-served manufacturing was gone.
BTW, I notice your handle stands for one of my favorite little-known roads, CHTT. I worked in the heights for a few years and loved chasing trains through town on lunch. I worked at an office housed in a leased outbuilding of hte former Thrall Car plant 2, so there was always something going on just to the north on EJE or UP.
