unverified the Class 387 count: GTR and RAIL said in February 2025 that 387101–387114 would stay with Great Northern and the rest would move to Southern; not confirmed since, stabling sidings away from Hornsey (not confirmed, so not stated), the date in 1976 when British Rail trains first ran to Moorgate (Wikipedia only, so not stated)
