Hi Mike.
I ride Metrolink to work in Lost Angeles and they have some stored in the ATSF Coach Yard. There are a few 3x53' car sets.
The K-Line sets were 5x40', though the trailers were actually about 39'. They sold the cars in pairs, with the fifth unit available once you had two pairs (you sent in a coupon and some amount of money). The pairs normally came with a tractor to go with the trailers.
Joe:
The spines are die cast. I'm thinking I might have to invest in some drills and taps. I don't like the stock K-Line trucks and would switch them over to 100-ton roller bearing types. I'm also thinking about making a special carry case for articulated container car sets -- assembling and disassembling them at the club is a pain.
