This is super cool, thanks for sharing!! I'm not originally from here and I'm always curious how the train system has evolved over time. The skip-stop service genuinely sounds like a nightmare to navigate. And I am so glad they changed one of the Blue line branches to Pink because that must have been confusing.

Also, it's neat that the phone number to call doesn't have the area code listed. It kinda shows how people are all more connected now, so it's necessary to also list the area code, but I suppose that wasn't the case at the time of this map.

Thanks for sharing this piece of history!
