I will be in kingston on october 17, where is a good spot to railfan? also what is the best time to see the most trains...Thanks in advance for any info....
There can be a train at any time of day or night, but there tends to be a bunch in the morning before 10am and another bunch in the late afternoon through early evening.
Around CP90 is a good place to hang out. It is adjacent to lots of retail and restaurants. If the patio at Panera Bread is still open, its a good place to watch trains while you eat a sandwich. If the patio is closed, you can take a seat by the windows and still see the tracks.
There is a small yard in Kingston, but there aren't many viewpoints that aren't on private or CSX property. You can see most of the yard from the Flatbush Avenue (Route 32) crossing.
If you have more questions I can try to answer them.
