Transportation: Railway/Transit

Aldridge's transit work accounts for 50% of the company's annual revenue with recently completed projects totaling over $550M for various transit authorities. The Aldridge transit management team (Superintendent and above) collectively has over 200 years experience on the tracks, and includes all types of railway systems including light rail, contact rail and catenary systems.

Equipment innovation has allowed our team to overcome project challenges such as difficult construction access in subway tunnels or completing electrical installations during limited weekend track closures. The ability to safely complete challenging transit projects with minimal interruption to our customers is what makes Aldridge Electric stand out in the transit industry.
