In 2020, Canada relied primarily on rail for both domestic and international transportation of propane. With an anticipated increase in propane and natural gas transportation in 2025, railyard operators need comprehensive loading systems. Keep reading to learn more about how to design the best railcar loading system for liquefied petroleum gas (LPG) operations. 

The Problem: Hazardous Cargo & Strict Regulations 

When dealing with LPG loading and unloading, there are two important factors to consider. First, propane and other gases are difficult and dangerous to deal with. During transportation, the railcars are pressurized to keep the chemicals in a liquefied state. This allows for easy movement of a high volume of natural gas by rail. However, the biggest challenge is safely loading and unloading, as this substance can be highly volatile if not handled correctly. For example, if the railcar pressure is not carefully maintained, the LPG can become a gas again, resulting in a deadly explosion. 

Secondly, any company that stores, handles, or transports liquid petroleum products is subject to the regulations set out in NFPA 58, the Liquefied Petroleum Gas Code. This document helps mitigate risks, ensures safe installations, and prevents failures that could lead to fires and explosions. The complexity of these regulations, paired with the hazards of handling these chemicals, highlights the importance of proper and comprehensive safe loading systems from a qualified provider. 

The Solution: Safe Railcar Loading & Unloading Systems

If you plan to deal with LPG in your rail operations, you will need a fully NFPA 58 compliant loading station. This includes safe access to the top of the railcar through a loading platform, safety cage, and gangway. It will also need to feature automatic shutdown valves in case of an emergency such as a fire, leak, or railcar rollaway. Your system should also include tight connections, vapour recovery systems, and adequate fall protection. 

Finally, we recommend investing in a loading arm for all LPG operations. While hoses can be used, they are generally less preferable to loading arms due to efficiency and safety concerns. When developing your system, consider using one of the following loading arms:

• “Bull Horn” Loading Arm: A single arm that divides into dual connections. LPG railcars typically have three connections (two product lines and one vapour line). 
• “A” Frame Loader: Favoured for its flexibility, long reach, and easy maneuverability. It is ideal for loading racks that feature dual unloading lines. 

When all these elements are combined, you can rest assured that your railcar loading system is efficient, safe, and compliant.
