Engineering survey and topographic mapping for railway applications.
Intermediate CRS created in 2020 to assist the emulation of the ETRS89 / MML07 SnakeGrid projected CRS t(code 9373) hrough transformation ETRS89 to MML07-IRF (1) (code 9369) used in conjunction with the MML07-TM map projection (code 9370).
United Kingdom (UK) - on or related to the Midland Mainline rail route from Sheffield to London.
