The controls of the car
A PCC was driven with the feet: a power pedal, a brake pedal, and nothing moves unless one of them is down. The game gives you the controller's four power and four brake notches, the gong, sand for a wet hill, the doors, and an emergency stop that drops the track brakes.
At a junction in the seventies the overhead contactor sets the switch: coast under it to go straight, take power under it for the curve. In 1993 the LRV carries a route selector and the points set themselves for the route it is programmed for.
Lines where they ran
Track, stops, grades and speed limits follow the real alignments, checked against aerial photographs of 1982 and 1993, period timetables and route tables. The streets, rivers and hills come from OpenStreetMap and survey elevation data, and the landmarks are modeled from photographs: the tunnel portals, the bridges, the P&LE station, Kaufmann's clock, the skyline of the day.
Sound
Every sound is made as you drive rather than played from a recording: the traction motors' gear whine rising with the notches, the rail joints and frogs under each truck, flange squeal on the curves, the tunnel's echo, crossing bells, and the SD-400's compressor and air.
People and traffic
Riders wait at the stops, wave the car down, board and pay the Pittsburgh way: at the front door going into town, on the way out going home. Automobiles and PAT buses share the streets, traffic lights hold the corners, and the other cars on the line keep their distance and meet you at the passing sidings.
Weather and seasons
Day, dusk and night, with the windows lighting up and the headlight mattering. Rain makes the rail slippery and brings out the wipers; snow lies on the ground and the roofs. There are summer fairs, Christmas on Smithfield Street and a parade day downtown.
A career
Seniority begins in June 1978 at the bottom of the list. Training with an instructor, the extra board, turn-in reports on pink copy, a record card with points against it, overtime calls, letters from riders and, in 1985, school for the new light rail cars.
