Why did you assume there would be no tail tracks at Whielie? I would have assumed that they would have built them.

I never made such an assumption. I figured they were only going to build the pocket track and put bumper posts beyond the turnout on the west end of the pocket track interlocking. That was the configuration at Farragut North and Silver Spring before the routes were extended further north.
