Getting pretty good along the Milwaukee North Metra line, but I have to force into lte only mode just to get 4g. Getting6-7 mb down though. Had good speeds at the Libertyville station. No service at Lake Forest which is typical anyways, super slow at the Deerfield station, then it picked up at Lake Cook and was good all the way down to Morton Grove. No more 4g south of Morton Grove
