goods shed

noun1

1. •
   A building in a railway goods yard for the storage of goods before or after transport by train, typically with a track running through it to allow goods wagons to be unloaded under cover, although sometimes they were built alongside a track with possibly just a canopy over the door.

   • And it wasn't just station buildings - workers' cottages, stationmasters' houses, signal boxes and goods sheds largely survived at a time when main line intermediate stations were being demolished. — 2021
