Give train passengers rights to compensation if trains are overcrowded

Many train journeys are overcrowded. There needs to be a greater incentive for train companies to invest in extra capacity. Requiring train companies to extend schemes for compensation for delays to provide compensation for passengers on train journeys which are overcrowded would give train operators more of an incentive to stop overcrowding. Train companies often make large profits, and many are owned by foreign governments, so should be investing to prevent overcrowding. Requiring compensation should encourage this.
