An old Boston T map peeks out from underneath the broken remnants of a recent edition, somewhere along the Orange Line in May 2013. It’s interesting to see that while the two maps occupy the same physical space, their use of it is much different. The older, simpler map fills up its space with bold lines and large type, while the modern map is more geographically based and complex – with the addition of bus routes and the Silver Line – and the type on it is correspondingly smaller.
