I have some bias since I live right near he UP/North line (when not at college in Washington DC) so I know more about it than the other metra lines. What I do know is that from Ogilvie up to the northern border of Cook County (Braeside) there are 10 grade crossings. The line is grade separated from Ogilvie to Evanston Central, and then it descends to grade level (which it reaches at Kenilworth; Wilmette is on a low embankment), then goes onto an embankment, followed by a trench up to Glencoe. North of Glencoe it is all grade level except for a over/underpasses. In that section there are 6 grade crossings in between Evanston Central and Kenilworth, and 4 in between Hubbard Woods and Braeside.
Getting to the point, if at least most of these crossings could be removed, and in an optimal (but infeasible or practical as well as financial reasons) world, you could end up with a grade-separated, dedicated passenger line (except for a few work trains from time to time, there is no freight on the line south of Lake Bluff) for the first 1 miles to Milwaukee. Note the key terms in that: grade-separated, dedicated passenger line.
All you need is overhead wires and you could end up with true HSR (albeit with some limitations; there is a good amount of freight traffic north of Lake Bluff, so only about 25 miles could end up being true HSR. You would need to add passing tracks to allow trains to go at higher speeds. I know for a fact that three crossings, Oakwood Avenue (Wilmette), Central Avenue (Wilmette) and Forest Avenue(Wilmette), could be removed easily and with little harm to road traffic flow. Three of the crossings are immediately next to stations that are at grade level (Kenilworth, Glencoe, and Braeside). Several other grade crossings have the road rising or lowering by 8-12 feet to reach the rail level; in these cases grade separation would be easy.
