Others have clarified the use of the Buena yard to interchange with the Milwaukee's Lakewood line. The Weber line's connection with the CTA snuck through property owned by Niles Gas, on a spur that started just north of where the weber line crossed under the Skokie Bypass. It connected inside the Skokie Shops complex. In later years, the CTA was the northern-most customer on the line, and its connection was last used was in 1987 when the North Western delivered the last of the 2600-series L cars (also last railcars built by Budd), after which the line was cut back further south.
All 3200-series cars were *trucked* to the CTA from Hornell NY. I used to see them being delivered two at a time through the streets of Morton Grove in the early 90's, with the destination signs dutifully displaying "Not In Service." When the 2400s and 2600s were sent out to Hornell for rebuilt, I believe they all moved by truck as well. The same will likely be done in the future, as CTA prefers to receive all new equipment at the Skokie Shops, rather than set up a facility at 63rd to do the same.
As a footnote, I am looking for ANY good pics of the flat cars used to deliver the 2600's, as I have visions of building a pair of the IHP cars as a load. See
