Back before CN abolished Sarnia to Port Robinson trains 330 and 331 we used to be treated to a mid day Westbound freight on the Dundas Sub daily.  331 was a freight that often ended up with interesting power and was an easy one to chase due to it working Paris Ontario to lift SOR traffic.  On February 11, 2016 I found myself standing at Copetown Ontario waiting on 331 with CN 2010 and CN 5462, a pair of standard cabs...not too shabby.  As soon as the head end passed me I highballed for Garden Avenue, beating them there by 5 minutes for a second shot.
