If you’re taking the morning train to Jefferson City, St. Louis or other points east of Kansas City, you’ll need to leave a lot earlier for the next few days.

That train, the Missouri River Runner No. 314, normally leaves Kansas City at 8:15 a.m. with an 8:34 stop in Independence and a 1:55 p.m. arrival in St. Louis.

But the Union Pacific – whose tracks Amtrak uses – is doing maintenance work that has forced the rescheduling of many trains. Starting Saturday, No. 314 will run 75 minutes early, leaving Kansas City at 7 a.m., stopping in Independence at 7:19 and arriving in St. Louis at 12:40 p.m. That will be the case through Oct. 8.

Also, Amtrak has been running its afternoon trains two hours later. No. 311 at the moment is leaving St. Louis 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.

All routes are scheduled to go back their regular schedules Oct. 9.

The Union Pacific is doing $5 million in maintenance work on its 35 miles of line between Independence and Pleasant Hill, replacing rail, replacing thousands of ties and laying thousands of tons of rock that serve as ballast on rail lines.
