The HR5000 is an electric multiple unit rapid transit car ordered from Hyundai Rotem for the Los Angeles Metro Rail's B and D lines.

As of 2024[update], the Metro Rail subway fleet is at least 26 years old, with the Breda A650 trains built in two batches between 1988 and 1997 and new CRRC HR4000 which are still in production.

[5] Construction delays for trains were caused by supply chain issues as a result of the COVID-19 pandemic, as well as compliance with the Uyghur Forced Labor Prevention Act.

[9][7] In December 2022, Metro began procuring new subway trains with a request for proposals.

[13] Although Hyundai Rotem's bid was more expensive than Stadler, Metro indicated that the contract was not solely awarded on price.
