Mike W - In the July 1970 TCA Train Collectors Quarterly, there is an article entitled
"Lionel - Alive and Well in Mt Clemens, Mi" mostly about the Mi operations but it does mention accessories, O-27 track and switches and also O gauge track are planned to be made at the Hillside facility. Interesting article about the early days of Lionel-MPC.
TCA members can download any Quarterly thru the TCA website.
