The Union Pacific is doing maintenance work on its line between Independence and Pleasant Hill, and that’s altering Amtrak’s Missouri River Runner schedule for the next couple of weeks.

One noticable change is for the train coming out of St. Louis in the morning, No. 311, with a mid-afternoon stop in Independence on its way to Kansas City. That train is leaving St. Louis two hours later, at 11:15 a.m., stopping in Independence at 4:20 p.m. and arriving in Kansas City at 4:55.

That same train turns around at Union Station and becomes No. 316, normally leaving Kansas City at 4 p.m. on its way back east. Now that train is leaving at 5:55 p.m., stopping in Independence at 6:14 and arriving in St. Louis at 11:35 p.m..

The morning train leaving Kansas City at 8:15 and stopping in Independence at 8:34 is less affected. That train, No. 314, is on its regular schedule for now but for eight days – Oct. 1 to 8 – it will leave and hour and 15 minutes early. That means a 7 a.m. departure from Kansas City, a 7:19 stop in Independence and a 12:40 arrival in St. Louis.

The afternoon train out of St. Louis, No. 313, is the least affected. It will still leave St. Louis at 4 p.m., stop in Independence at 9:06 and arrive in Kansas City at 9:40, but it will depart Sedalia at 7:39 instead of 7:32.

The regular River Runner schedule is to resume Oct. 9.

The Union Pacific is doing almost $5 million in maintenance on the 35 miles between Independence and Pleasant Hill. Crews have been busy in Independence all week. That work includes replacing 21,800 ties, replacing more than a mile of rail at various curves, working on the surfaces at 44 road crossings and laying down 16,000 tons of rock on the roadbed. The work is to be done by mid-October.
