Analysis of the test posts is complete.

The 3 most popular metro and intercity rail systems in the US are Amtrak, California High-speed Rail, and the BART.

The Least popular are the LA Metro, The Seattle Link and MARC

Based on this we can conclude that Intercity Rail is far more popular than local rail. Additionally the West Coast is much less popular than the East Coast.

Next data test should include METRA, Long Island Railroad, Brightline, and Metrolink to establish more clear modes. Additionally future data collection endeavors will exclude the Portland Street car in favor of MAX
