An intermediate block post is a Class C station similar to a block hut on a double line, however in this the signal corresponding to the block post is actually controlled by the signal cabin at the station to the rear, and the intermediate block post is not manned at all. See intermediate block section. The terminology 'Block Hut' in contrast to a block post is often taken to imply that the station or halt is manned.

E.g., on the Howrah - New Delhi line, the Dhanbad - Mughalsarai section (especially around Gurpa - Gujhandi) has many block huts, in some cases with practically every other station or halt being a block hut.
