Manhattan is a moderately sized city with plenty to offer. It is nestled in The Flint Hills and not flat like most Kansas towns. The capital Topeka is about 50 miles to the east, Salina is about 65 mile to the west. You can get here from Topeka by taking 24 to the west, go past Saint George until you start to see a lot of restaurants and stuff. Once you see a bridge it will have a sign that says ''Big Blue River'', a three span bridge will be to your left. Continue a little farther until you get to Levee Drive and make a U-turn get back on 24 eastbound, there will be a dirt parking area just before you hit the bridge. Go down there and park, the train track will be to your right. There is a area before the train bridge where the tracks intersect the trail, by standing on the trail you can get some pretty good photos and video. There is also a boating ramp you can walk to watch trains cross the bridge if you'd like. The single track mainline called the Union Pacific Salina Subdivision or The KP line
( Old Kansas Pacific) is owned the the Union Pacific, with mostly unit coal trains. You can expect to see unit grain, manifests, autorack, and a local, in some rare times UP transports military vehicles to and from Fort Riley. Sometimes you can see some pretty cool stuff, like I witnessed about a three week span of trains transporting HUGE red pipes. The line is used by any where from 1 to 15 trains a day, The norm is about from 3 to 7 though. Manhattan has plenty other railfanning sites though, like a hotel that is not even two car lengths from the tracks. Just stay on 24 and Tuttle Creek BLVD the tracks will parallel you and you will find many grade crossing opportunities.
