You can spend the whole day here. It's not uncommon to have 5 or 6 trains waiting to make their move. I like the crossing at center street which is marked by the blue arrow. I also like the New Haven connection which is marked by the red arrow. The picture of MRL 256 was taken there.
Traffic is usually busiest in the morning.
From here you can follow NS south to Attica Jct. where CSX crosses, or follow NS west to Fostoria.
