I don't completely understand what you are asking, but I'll give it a shot as a Super O user when it was "new" 1958/59 (and so was I). The #145 used either a #145C controller, a sort of switch which went under the track ties; or an insulated outer rail which acted as a switch via the train cars trucks. There are special SO insulated outer rail sections (No.48 tracks). Look for straights with no metal jumpers on the underside between outer rails on straight sections. They are what I am referring to. You may have some and not realize it!
The # 153 used a #153C controller, or an insulated rail and a radio shack relay, of sorts, to switch from green to red and red to green.
The #145C and#153C fit fine under SO track. No problem!!!!
The #3562 Barrel Car (1954) used some special lockons (#OTC-1) for O and O27. there was a SO special part ( #36 Remote Control Blades) which was made for this purpose but good luck finding them. They could be fabricated with some creativity and courage. The #362 Barrel loader (1952) is an "on-off" item, see below. It does however have a disc rectfier which is known to die in middle age (after 30 or 40 years), If yours simply buzzes at you or does nothing, that is most likely the problem.. It is an easy fix with an modern epoxy recifier, however.
The other on-off stuff such as the oil derrick, beacon, coal loader, water tank should not be "track type sensitive" assuming that you are not using a lockon to power them up... which is a bad idea anyhow!
I don't specifically recall a #2065, Greenburg lists it as part of the 665,685 & 2056 from 1953 and 1954. I'm only guessing, but the pickup rollers may not like the lower power rail on SO.
Can't help you on the Bascule bridge. It was originally an early 50's item (#313) which was too expensive for my dad or my juvenile allowance.
I loved SO, and the fact that the outer rails and pins match up perfectly with Gargraves and Ross track is great. Hope this helps!
