I asked some questions about the new WP&Y passenger cars and got the following reply:
"In regard to the new coaches, the price is between us and the manufaturer. The trucks are roller bearing and built by Team Mfg. formerly Thiessen Mfg. in Langley,B.C. ..Hamilton Mfg. & Hamilton Construction are owned by the same individual. Hamilton Mfg. has built railcars for other railroads besdes the WP&YR. Hope this answers your questions."
Incidentally, Hamilton Construction is a Skagway Company, and apparently don't have a lot of work in ther winter so they have their subsidiary do other jobs, such as building passenger cars.
