JMD has been involved in the development of major rail infrastructure projects designed to enhance goods movement and passenger service in the region. Major goods movement projects include the Alameda Corridor and Alameda Corridor - East grade separation program, designed to increase rail capacity and provide uninterrupted operations between existing ports and domestic destinations. Projects designed to enhance passenger service in the region include Metrolink's service expansion program.
In addition to goods and passenger movement, JMD has served railroads serving the nation such as the Union Pacific Railroad (UPRR) and Burlington Northern Santa Fe Railway (BNSF). In fact, JMD began serving the Union Pacific Railroad (UPRR) as expert engineer and witness throughout the state of California. Since then, JMD has served both UPRR and BNSF on similar projects intended to address safety and rail operations.
Since its inception in 2001, JMD has become a recognized leader and expert in the design of railroad corridor crossings, grade separations and quiet zones in the region.
