Case Studies Studies in continually exceeding expectations

Locomotive Facilities

Whether high speed commuter rail, transcontinental passenger rail or diversified commodities rail lines, MJK has worked at numerous railroad facilities in the area. Providing remediation services, pipeline installation and design/build of high capacity fueling systems, MJK offers a diverse range of experiences to our railroad clients.

Current regulations governing the fueling industry are mostly geared toward retail fueling and oftentimes do not address the specialized needs of the railroad customer. MJK has worked closely with regulatory agencies to resolve these differences insuring compliance and appropriate application of technologies to these high delivery rate systems. With the fueling component market geared to low volume fuel dispensing, MJK recently worked with component manufacturers to develop specialized parts necessary to meet system needs and regulatory demands.

Some of our most unique projects have come from our work at railroad facilities. With stringent operational and safety restrictions, MJK provides a unique mix of capabilities to this industry with leading design innovations and professional installations.

Case Study: Amtrak - Public Mass Transit


Project: As a precursor to planned expansion of the Soto Street Amtrak Maintenance yard, the client needed to remediate existing ground contamination, reroute existing sewer lines, and install temporary fueling systems in advance of major development at the site.

Challenge: Working in an active train yard presented challenges to work schedules and approach to insure the facility operations were never impacted by our work. Insuring safety of our crews working between active rail lines was of utmost importance in this project.

MJK Solution: MJK approached the work by assessing the various tasks to be completed, and scheduling similar activities to streamline the work effort and optimize labor and equipment hours. In demonstration of the diversity of our capabilities, MJK performed remediation of crude oil found at shallow depths on the site, repaired active crude oil lines, tapped exiting sewer lines and re-routed approximately 800’ of 24” RCP sewer piping, relocated on-site sand towers and locomotive related equipment, installed a 12,000 gallon aboveground fuel tank and related locomotive fueling equipment, and graded and bedded approximately 1 mile of track bed.

Case Study: MetroLink Design/Build-Public Mass Transit


Project: As part of the expansion of commuter rail service to the Inland Empire, development of local service facilities for rail equipment was needed. As part of this development, a high flow fueling system was necessary to support the facility.

Challenge: Due to the proximity of the proposed fueling system to haul routes, property lines, overhead high power lines, existing and planned underground utilities, and location of rail tracks, the work area and placement footprint for the fueling facility was severely restricted.

Further challenges to the project arose as a result of conflicts between existing state and local regulations and the projects needs. Existing regulations and state approval components are more applicable to lower flow fuel systems. MJK staff was required to meet with local agency representatives and speak with state agency representatives to resolve these conflicts.

Final challenges resulted in the unavailability of system components which would accommodate the large diameter piping required to meet flow requirements.

Outcome: MJK installed shoring to facilitate work in the restricted area, designed and built a multiple tank storage system combined with high volume pumping equipment to supply remote fuel cranes necessary to fuel the rail equipment. Our staff met with local agency representatives and spoke with state agency representatives to resolve the conflicts in the regulations. MJK worked with local manufacturers to design and develop the specialized components necessary to complete the project.
