I found out that two 2100 series units would be in the consist of yesterday's westbound, I decided to get a shot of them when I finished work.
I finished work, and waited. After about an hour, I heard them, as they were about 5-6 miles away. I set up shot, and waited a few minutes. Here's the result:
I was happy with the result. Normally I shoot on the other side of the track, but today, I shot on the other side, a good choice.
