Howard Street Tunnel Expansion

Project Context

The Howard Street Tunnel Expansion project consists of improving vertical clearance along the rail corridor to allow double-stack trains (trains carrying containers stacked on top of each other) to travel between Baltimore City, Maryland, and Philadelphia, Pennsylvania. The main obstacle to double-stack service along this corridor has been the Howard Street Tunnel, a 1.7-mile-long railroad passage under the heart of Baltimore City that was originally built in 1895. The tunnel vertical clearances are currently restricting the ability to move double-stack trains along this section of the network, including to and from the Port of Baltimore.

This complex construction work requires precise efficient monitoring and data management to avoid any potential risks to the surrounding assets and communities.

The Howard Street Tunnel Expansion Challenge

To provide some context to explain the current challenge facing by the Howard Street Tunnel expansion project, we must recall the 2001 accident. That year, a 60-car freight train derailment occurred in the Howard Street Tunnel in Baltimore City.  The derailment caused a chemical fire that practically shut down the downtown area, as it also caused a water main to rupture, causing major flooding in the streets above. The accident disrupted rail service on the Northeast Corridor. It also slowed Internet service in the U.S. for several hours due to the destruction of a cable running through the tunnel.

If any expansion of such an old tunnel could create reticence among the communities and asset owners of nearby structures, we can imagine the magnitude of these concerns in a population that remembers the 2001 incidents.

Given this context, the Howard Street Tunnel Expansion project faces the challenge of vertically extending a 100+ year old tunnel while preserving the stability of the infrastructure that is built above and around the tunnel, with minimal impact to nearby residential areas and the stability of the railroad tracks that will carry the two-stack container freight trains.

Overcoming Construction Monitoring Challenges

To maintain the stability of the infrastructures during the expansion, it was necessary to place sensors and monitor the data collected by them. In this way, the team in charge of the expansion and the project stakeholders would be able to make an exhaustive control and take the necessary preventive measures in case any alarm is triggered.

Before Proqio came on board, the Howard Street Tunnel expansion was struggling to find a complete solution that could collect data from over 1,000 instruments and analyze it in real time to ensure asset integrity during the expansion project. The other monitoring methods they were evaluating were cumbersome and not suitable for such a complex project. The team needed a solution that offered real-time monitoring, data integration from several sensors and comprehensive reporting to ensure the project stayed on track and met safety standards. That's where Proqio comes in.
