Repairing a Leaking Main Under Railroad Tracks
Industry: Gas Distribution
Location: Baltimore, Maryland
Client: Baltimore Gas & Electric
Pipe Diameter: 20″
Business Areas Addressed:
- Gas Remediation
- Total of 18 joints were sealed
- All gas leaks were monitored after sealing and eliminated
- No disruption to major transportation pathway
A gas main with leaking joints that is located under railroad tracks is an exceptionally challenging problem for any gas utility. The organizations responsible for railroad activities do not allow any excavation within approximately 20 feet of the tracks to ensure that major transportation pathways are not disrupted. Obtaining permits and approvals to excavate within that zone would require BGE to acquire special permits to stop commercial and consumer rail activity for several hours.
A total of 18 joints were sealed in the 20″ cast iron gas main. Following the CISBOT project, BGE monitored the gas leak and closed the leak folder. This project gained attention within BGE and its parent company, Exelon.
