I have the little red book, CERA's Bulletin 105, "The Great Third Rail." Keeping in mind that it was published in 1961 and the status of some cars may have changed since then (308, now at IRM, is one I know of), here is the disposition list from that book:
11 -- RELIC, South Elgin, Ill.
20 -- RELIC, South Elgin, Ill.
36 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
303 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
308 -- Indiana Museum of Transportation and Communications, Indianapolis, Ind.
309 -- Illinois Railway Museum, Union, Ill.
315 -- Railways to Yesterday, Rock Hill Furnace, Pa.
316 -- RELIC, South Elgin, Ill.
317 -- RELIC, South Elgin, Ill.
318 -- Indiana Railway Museum, Westport, Ind.
319 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
320 -- Iowa Railway Historical Museum, Centerville, Iowa
321 -- Illinois Railway Museum, Union, Ill.
409 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
431 -- Illinois Railway Museum, Union, Ill.
434 -- Seashore Trolley Museum, Kennebunkport, Maine
451 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
453 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
458 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
460 -- Columbia Park & Southwestern Ry., North Olmstead, Ohio
"In addition, four Fox River Line lightweight cars were purchased by the Columbia Park and Southwestern Ry. thirdhand from the Shaker Heights Line in the 1950s. The cars are the 302, 303, 304, and 306. All four are on the North Olmstead, Ohio, property.
"All other CA&E cars were cut up and sold for scrap by 1963."
No, I can't explain why it says 1963, yet the book was supposedly published in 1961. And in case anyone can't figure it out, RELIC is now the Fox River Trolley Museum and the CP&SW is now Trolleyville.
