Today, the schedule suggests closer to 5.5 hours. He discussed 90 mph max speeds dropping 30 minutes of that time. If a 10 mph faster speed drops 30 minutes, it seems proportional to suggest a 30 mph faster speed would drop 90 minutes - to 4 hours or so.

But let's do the math for the best case scenario.....
284 rail miles / 5.5 hours = 51.6 average mph
284 rail miles / average 61.6 mph = 4.6 hours (adding 10 mph to average)
284 rail miles / average 81.6 mph = 3.5 hours (adding 30 mph to average)
Of course the best case scenario is not what you should expect in real life. For instance, the 27 rail miles Alton to St. Louis and the 37 rail miles Joliet to Chicago will not be seeing the higher maximum speeds because those tracks were not rebuilt. Never-the-less, the method of using the existing average speed of the train and increasing it by the difference of the maximum speeds is very, very generous for calculating the elapse times for the faster trains, which is why I usually suggest the best case scenario.
Bing suggests the driving time between Chicago and St. Louis to be 4.15 hours.
The sweet spot for trains and cars o compete with flying is with the train taking less than 3 hours, and with the car taking less than 6.5 hours.
So, in the Chicago to St. L:ouis market, the vast majority share will be taken by cars.
