Of the two Inclines -- the Duquesne and the Monongahela -- the Duquesne is way cuter. It has cheery red and yellow cars inching up and down Mount Washington like party hats. The Mon's cars remind me of Dickensian funeral carriages: black and brown, with tar paper? leather? stretched over the tops. The Duquesne's cars are open and airy. The Mon's are compartmentalized. The Duquesne has a little museum at Upper Station. The Mon just has...a station.
But. The Mon is still worth the ride, if only to compare the two Inclines, which is what husband and I did. We parked at the Duquesne Lower Station, rode it up Mount Washington, walked down Grandview Avenue to the Mon, and rode it down Mount Washington. The views are just as good as the Duquesne's.
At the bottom of the Mon, you end up at super commercial Station Square. The walk back to Duquesne Lower Station along the river, with a stop at the Clinton blast furnace, is quite enjoyable.
