Ok, I did some good old-fashion 'on the ground' surveying. Went to greenwood, walked around the north and east, there doesn't seem to be anything out of the ordinary, so much is there nothing out of the ordinary that I think greenwood might not be receiving the new cars at all. More on that in a bit..
I also climbed up to the rail-line, just after a go train zoomed by, at the overpass over greenwood ave... From there I was able to look at two things: a. the south part of the yard, and b. the 'siding' where greenwood would take a rail delivery.
For a, again nothing out of the ordinary.
For b, the siding is definitely derelict. It looks like it hasen't been used in a very long time, tops of the rails are rusted out, and there is *extreme* overgrowth of grass (about 4-ft high) right across the rail alignment. I cannot see as far as the switch to tell you if it is still physically tied in with the mainline, but if they were somehow expecting to receive the new trains by rail here, they would have this siding cleaned up by now, and they didn't, so they won't.
Passed by wilson both yesterday and again today. Noticed yesterday that south-end rails to the new carhouse are in place, the ballast is being poured now. Also of note is a pair of diesel shunting locomotives parked on the eastern track leaving the south portal of the new carhouse. Those locomotives were sill there today. Keep in mind that these new cars are shipped unattached by truck, they cannot, unlike the Ts and Hs operate on their own power (cockpits only in front and back cars), so they will need to be hauled by a diesel shunting locomotive before they are probably all brought into the new car house, where I suspect the assembly will take place.
So in conclusion: no sign of the new cars yet, but a high likelihood that wilson will take delivery and assemble the trains. This also makes important sense considering wilson's proximity to the 401...
