All 3 were 7Ks, one 8 car train, and two 4 car trains. Progress!


Interesting. Startup testing was done in the past with a combination of 1 and 2k cars to establish a baseline to compare against previous startup testing.

That could have be the case here too. I used to take the Greenway daily but not anymore, so its possible I missed some earlier testing.

When I say compare against previous startup testing I mean startup testing on previous new segments going back to the 1980s. The performance profile of the 7k cars is different then the older rolling stock.
