***THIS IS AN UPDATED VERSION***
ALL CHANGES ARE INDICATED IN RED, BOLD WRITING.
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 all Wolverine services terminating in Detroit at MCS. Detroit -- New Center, Troy, Royal Oak, and Pontiac can be served by frequent DMU commuter rail service.
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 GRR and CHI, mirroring 370/371.
Add 374/375 and 376/377 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 as the reincarnation of the Lake Cities, 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.
Reroute the LSL via the Michigan Line and Canada to Boston. Forget splitting at Albany. Shorter station stop will shorten the running time. Also, this will be a SECURED TRAIN while traveling through Canada to expedite the border-crossing process. The goal is to give customs officials at Niagara Falls a full list of passengers and crew ahead of time so the passengers can be checked against the list and the train can receive a quick inspection before re-entering the US instead of a long, drawn-out process that killed off the International.
Broadway Limited between NYP and Chicago, in LSL's old time slot.
Add a second frequency for qualifying National Network routes. Qualifying routes would have to have sufficient ridership and available equipment and crews, as well as being cost-effective and would depart twice a day, once in the early afternoon (1-2 PM, allowing for morning corridor trains to connect) and once in the evening after dinner, perhaps 7 or 8 PM, allowing mid-afternoon trains to connect. Possible candidates include the Coast Starlight, Empire Builder, Lake Shore Limited, etc.
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.
Reinstatement of the Black Hawk, Chicago to Dubuque, IA.
Implementation of service to the Quad Cities as the Quad Cities Zephyr.
Additional trains for the Lincoln Service.
An additional pair for the Missouri River Runner.
Prairie Star (KCY-DEN).
Front Range Limited, route TBD.
Extending the Heartland Flyer to Kansas City via Wichita and Newton, KS.
Direct rail connection between the Pacific Surfliner and Capitol Corridor services. Currently, this section is only served by the Coast Starlight, creating a gap in corridor service. Creating a specific LA to Oakland service could prove useful to relieving pressure on local highways.
