Switchers with Flexicoil Trucks

Which railroads owned early EMD switchers (pre-SW1500) with Flexicoil trucks? So far I know Pickering Lumber's SW900's, Rock Island's SW1200's, and New Haven's SW1200's had Flexicoils. Any others? Thanks.

CN and CP had fleets of SW1200RS units with Flexicoil trucks, frame-mounted handrails and larger numberboard assemblies.

Illinois Terminal had a dozen SW1200s with the Flexicoil trucks. I believe Great Northern may have had some too.

Thanks for the replies guys.

of BN 162 (ex GN 29) and BN 165 (ex GN 32) sporting Flexicoil trucks. Both units are SW1200s built in 1957.

There were numerous older switchers with these trucks. GN had SW7's and SW1200's with them. MN&S SW1200's, GTW SW1200's, RF&P had 3 SW1200's with them. Relco has changed the trucks on ex ACL SW9 1253.
