I have taken the "Rapid" many times over there years. I never fully understood why it is called the Rapid as it stops for automobiles. If it were a true rail system like Chicago, the cars stop for it. Be careful on some of the lines at night as the riders get very scetchy. I have witnessed two fights over the years and both times was terrified.
The city of Cleveland wonders why it loses money year after year. How about because it works on the honor system! For instance, I rode the Red Line from West 25th station to the Airport. There was no ticket checker or turnstyle at either stop. Yes I paid the $2.25, but after I realized I could have just done it for free. How many residents from the East 40th to East 170th block of Cleveland are taking advantage of this?
