(WZZM) - Amtrak service from Pontiac to Chicago is returning to normal after several weeks of service interruption. Work is finishing up on track lines between Kalamazoo and Porter, Indiana that will allow trains to travel 110 miles-per-hour. "There are a few sections that still have 40 mile-per-hour slowdowns, but for the most part the line is back up to speed," said MDOT spokeswoman Janet Foran.
The state is expected to complete the purchase of 135 miles of track between Dearborn and Kalamazoo this summer. The aim is to get speeds on that section up to 110 miles-per-hour in the future.
A slow section of track between Porter, Indiana and Chicago is receiving a $3.2 million dollar federal grant to speed up passenger travel times.
Passengers with Amtrak reservations should confirm train times at Amtrak's website.
