Omaha

The largest city in Nebraska currently has a basic bus network and a single recently-added bus-rapid-transit line that constitutes "the most significant mass transit investment this region has seen in decades". So you can see there is quite some room for improvement. The proposed network includes 5 lines that serve the surrounding suburbs (including those in neighboring Iowa), the state capital at Lincoln, the Amtrak stations (service to Denver and Kansas City), and the waterfront. 

Lines

• Red: 29 miles, 12 stations
• Green: 36 miles, 12 stations
• Cyan: 6 miles, 5 stations
• Blue: 39 miles, 14 stations
• Purple: 66 miles, 23 stations

 

Kansas City

 Spanning two states, Kansas City is another one covered with train tracks. It does include an Amtrak station with service on two routes to St Louis, Chicago, and Los Angeles, but its rail transit is restricted to a recent light rail with shared right-of-way stretching from Union Station through downtown. This map uses those two endpoints as a jumping-off point to connect to five new lines. In order to show the line rail line along with the added commuter rail, the downtown area is stretched north-south. 

Lines

• Orange (light rail): 2 miles, 9 stations
• Red: 50 miles, 16 stations
• Cyan: 45 miles, 15 stations
• Yellow: 35 miles, 14 stations
• Green: 54 miles, 15 stations
• Purple: 52 miles, 26 stations
