Crush loads are normally measured using number of standing passengers per 1 square metre (1.2 sq yd).
[6] In India, the term "super dense crush load" [7] has been coined by railway officials to describe passenger loads on peak-hour trains operating on the Mumbai Suburban Railway when carriages built for 200 passengers carry over 500, translating to 14–16 people per square metre; not accounting for the many passengers who have no choice but to hitch onto overcrowded moving trains out of necessity.
[8] Crush loads in transport vehicles can result in many secondary issues, such as petty theft and pickpocketing, extreme discomfort for passengers, sexual harassment, and an inability for passengers to board and alight vehicles in a timely manner.
[3] Large dense concentrations of passengers can create dangerous conditions, both within transit vehicles and at overcrowded stations.
In 2014, a news service in Mumbai, India reported several serious platform gap mutilation incidents and a death within a few months, mostly attributed to crowded conditions.
