CRH

CRH is an acronym used for several distinct topics across transportation, industry, and science. The most widely recognized meanings are China Railway High-speed, CRH plc, and corticotropin-releasing hormone.

China Railway High-speed (CRH) refers to China’s high-speed rail services and the associated rolling stock introduced in the 2000s. The CRH network operates on key corridors connecting major cities, with trains designed for speeds up to 350 kilometers per hour on the most modern lines. The service is managed by China Railway and overseen by national transport authorities. CRH encompasses various classes of high-speed trains used on passenger routes across the country.

CRH plc is a multinational building materials company headquartered in Dublin, Ireland. It originated as Cement Roadstone Holding, formed in 1970, and has grown into a global producer of cement, aggregates, concrete, and related building products. Through a series of acquisitions, CRH has developed substantial operations across Europe and North America. The company is listed on major stock exchanges and is one of the largest building materials groups in the world.

Corticotropin-releasing hormone (CRH) is a hypothalamic peptide that stimulates the pituitary to secrete adrenocorticotropic hormone (ACTH). It plays a central role in the hypothalamic-pituitary-adrenal axis, coordinating the body’s response to stress. CRH is a subject of extensive endocrine and neuroscience research and is used in various experimental and diagnostic contexts to study stress physiology.
