Mon Incline, Pittsburgh PA

Monongahela Incline, Pittsburgh PA

The Monongahela Incline was the first passenger funicular railway built in the United States. Opened on May 28, 1870, it transports more than a half a million riders each year. A $3.5 million dollar major renovation was completed in 2015 that involved rehabilitating the cars, rails, ties and cable, and lift components.


The Incline has automatic sliding doors on both the stations and the rail cars themselves. Working on a historic landmark comes with many challenges. The cars lose power while travelling away from the stations so special wiring was required. Installation was also a challenge since many of the doors are inside the station at the top of Mount Washington with no level surface to work from.


Custom door headers were constructed to accommodate existing door panels on the rail cars. Special wiring and batteries were added to each door to safely keep doors closed until the cars are parked in the stations.

Automatic Doors and COVID-19

Automatic doors serve an essential purpose in healthcare facilities and more broadly across our communities: providing touch free access and egress. As the COVID-19 crisis unfolds, this purpose is even more critical. Through our joint efforts of providing, maintaining, and servicing automatic door equipment, our industry is helping to minimize the transmission of this and other harmful viruses which could otherwise be spread through the touching of contaminated door knobs, handles, etc.

Automatic Door Technicians, particularly AAADM Certified Automatic Door Inspectors, are on the front lines of ensuring proper operation and maintenance of these critical touch free access devices – working in healthcare facilities and other high-traffic areas where the risk of COVID-19 transmission may be elevated. Especially during these times, AAADM encourages automatic door technicians to follow these basic guidelines to stay safe:

For additional information and guidelines, consult the CDC website. All individuals are expected to take actions to reduce risk of transmitting the COVID-19 virus, and we thank the automatic door technicians for their key role in ensuring proper operation of touch free automatic door access devices.
