Crush load
high passenger vehicle occupancy leading to crushing
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.
Definition
In the context of transport economics and planning, crush load refers to the maximum level of passenger load for a particular vehicle or rail carriage. Crush loads are calculated for the number of passengers per unit area, standing up.
Crush loads are not an issue for passengers that are seated, as passengers will not normally sit on one another.
Crush loads are most common on city buses and rail metro systems, where passenger loading is high, and most passengers stand. Airlines almost never have crush loads, nor do high speed and/or long-distance rail or long-distance bus routes, where all passengers are generally seated.
Crush loads are normally measured using number of standing passengers per 1 square metre (1.2 sq yd).
“Crush load” enters the record as high passenger vehicle occupancy leading to crushing. Crown Archives preserves that source wording while asking what Crush, load and high can confirm, complicate or overturn.
Why this record matters
“Crush load” is worth following because a concise public description often conceals a longer documentary argument. Here, Crush, load and high provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jan 9, 2024. The linked authority identifier is Q16953040. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
