Huge problem: natural gas is not allowed in many tunnels.
Interesting. Does this exclusion apply to a bulk storage/transport situation, or as part of a vehicle's fuel system?
Many times, trucks transporting bulk fuels of various, or any, kinds, as well as various other bulk hazordous materials, which are not fuels, are not allowed in tunnels. However, some of those same fuels, when installed as an integral part of a vehicle's engine fueling system, or as a fueling system for auxiliary engine-driven equipment installed on the vehicle, are allowed in tunnels.
