I could see a heavy rail line here. I'm a NIMBY, anti-train conservative, whatever you want to call me, but I could see it.
King Street Station to SeaTac Airport is either 13 miles and 38 minutes or 14 miles and 40 minutes elapse time, depending upon which web link you choose to believe. So here's the average speed.......
13/38 x 60 = 20.5 mph average
14/40 x 60 = 21.0 mph average

Using the most favorable average speed of 21 mph average speed, to go 32 miles it will take how many minutes?
32 miles /21 mph x 60 = 1.52 hours or 91.4 minutes.

Sounder trains take 55 tp 62 minutes to travel those same 32 miles, depending upon time of day and which direction you are riding.
32/55 x 60 = 34.9 mph average
32/62 x 60 = 30.9 mph average

So, in this one scenario, the commuter train will be around 10 mph average speed faster than the Link light rail trains, by around 30 minutes, or a half hour on the clock..
