Crush load

A crush load is a level of passenger loading in a transport vehicle which is so high that passengers are "crushed" against one another. It represents an extreme form of passenger loading, and normally considered to be representative of a system with serious capacity limitations. Crush loads result from too many passengers within a vehicle designed for a much smaller number. Crush loaded trains or buses are so heavily loaded that for most passengers physical contact with several other nearby passengers is impossible to avoid.
