Albany

The "Capital Region" surrounding Albany includes several additional cities which are small metros in the their own right: Troy, Schenectady, and Saratoga Springs for instance. This imagined system has connections to four Amtrak stations serving points north (Montreal), south (New York), east (Boston), and west (Buffalo, Chicago). While downtown Schenectady is served, the rail lines don't get within walking distance capitol buildings in Albany, so I've introduced two BRT shuttles from Albany-Rensselaer station (also serving Amtrak) and the new Ten Broeck Junction.

Winnipeg

Our first (and only) venture into Canada brings us to Winnipeg, Manitoba's capital and largest city, located at the convergence of the Red and Assiniboine Rivers. Our routes provide us connections to intercity trains and the international airport. I've added a light rail line along Main St and Broadway to connect to the capitol buildings and a new northern rail terminal at Chinatown.

Hartford

Connecticut's capital is on the verge of getting real life commuter rail. The NHHS Rail, or New Haven - Hartford - Springfield line, will connect to Metro North in the south on the Long Island Sound and stretch all the way into Massachusetts when it opens in 2018. While it essentially duplicates the Amtrak shuttle train, it includes a few additional stops and nearly quadruples frequency.  This map adds three additional lines, with numerous connections to Amtrak, Metro North, and Bradley Airport.

St Louis

St Louis is not the capital of Missouri, but as a metro area is home to half the state's population. Its two existing light rail lines serve both its airport and its downtown Amtrak station (which has been experiencing substantial growth in ridership in recent years). The new rail lines serve this central station, as well as the westerly Kirkwood. Both the light rail and the new lines cross the Mississippi river into Illinois.
