Although the improvements are expected to be finished this year, exactly when the new 110-mph maximums actually will begin is hard to pinpoint, officials say.
It could be sometime next year. But timing depends on testing of a new type of signaling system on the line, which Amtrak shares with freight trains.
Richard Harnish, of the
Midwest High Speed Rail Association, said the system includes positive train control. That will use radio and GPS technology to help monitor trains’ position and speed. “They have to be very conservative with testing,” he said.
... speed isn’t the project’s only benefit. ... better train flow and increased reliability. In other words, fewer delays that sometimes make current trips longer than the scheduled five-and-a-half hours.
... much of the line is a single track that accommodates passenger and freight trains in both directions. To reduce delays, double-track segments and passing sidings have been added or lengthened so two trains can run simultaneously in more areas. ...
