Problems surrounding public transport during the Rugby World Cup games in Cardiff are to be examined by a National Assembly Committee.
The term 'travel chaos' was used on numerous occasions, with many fans reporting delays and overcrowding when travelling to and from the capital.
The Enterprise and Business Committee will speak to representatives from Great Western Railway, Arriva Trains Wales, Network Rail and Cardiff Council, as well as the organisers of the tournament, to work out what impact the travel issues had, and whether anything can be learned for future events.
It's thought the economic value of Cardiff's contribution as a host city is worth more than £300 million pounds.
The travel companies involved apologised to customers for any inconvenience, and said they had put on as many services as possible.
