Uncovered at Orient Heights station, photo from 2009. Note “Washington” station instead of Downtown Crossing, the entirely different alignment of the Orange Line to Forest Hills, no Red Line extension to Quincy and Braintree (and it ends at Harvard in the other direction). The “A” Green Line to Watertown is still in service, and the “E” goes all the  way to Arborway. Love the elegant simplicity to this, and the lovely crimson red used for the Red Line (which goes to Harvard, after all!).
