MICHIGAN SERVICES:
Bring the International back, routed via Detroit to Toronto.
Add 356/357 and 358/359 to the Wolverine route on the holiday schedule. Utilize the renovated MCS in Detroit as a "mini-hub" for Amtrak, with 350-355 and 360-363 terminating there and 356-359 continuing to Pontiac.
Add 366/367 to the Blue Water route to provide mid-day service to that region. It's a real pain to get up on the weekend to go home and you aren't able to take CATA to LNS (since they don't start running until 10). Additionally, the 8:40 AM WB arrival interferes with class schedules.
Add 372/373 between DET and GRR over the CSX Plymouth Sub. This line sees very little traffic (a couple road trains, a local, and as occasional unit grain). Hand 'er over to MDOT/Amtrak and upgrade it for 110 MPH.
Turn MCS into a mini-hub. Sure, Ford owns the building, but since they're only keeping four passenger tracks, there's sufficient space to make an addition and move Amtrak's offices from Pontiac to the MCS. That would all have to be negotiated though.
360/361 and 362/363 as DET-TOL-CIN, connecting with the CL in Toledo and Cardinal in Cincinnati.
368/369 for a Detroit* to Traverse City service under the "Michigander" name, calling at Howell, Durand, Mt. Pleasant, Cadillac, and Traverse City.
*I say Detroit instead of GR because, although GR is closer, the infrastructure doesn't exist to operate directly between GR and Traverse City. Plus, GR is a stub-end station.
NATIONAL NETWORK:
Reroute the LSL via the Michigan Line and Canada to ALB and then split to BOS/NYP.
Broadway Limited between NYP and Chicago, in LSL's old time slot.
WISCONSIN/MINNESOTA SERVICES:
North Coast Limited (instead of North Coast Hiawatha to avoid confusion with the current Hiawatha), CHI-MSP on a schedule akin to the Wolverine's current schedule.
Expand the Hiawatha schedule to include two more pairs.
