Rule 261 has nothing to do with the fact it was manual block.

I guess, strictly speaking, they had Rule 261 period, with automatic block with the current of traffic and manual block against. Anybody know when that dates from?

However, on a lightly travelled branch such as the Far Rock or Long Beach. you can have 261 in it's primary direction, but manual block in the other direction. This is done as a cost cutting move for the rare occasion they do run against say like mid-day track work. It's only 1 train at a time within the block, but at least you can still run service. Its more equipment and inspection-wise to have it bi-directional/261 both ways, especially if crossings are involved.That isn't Rule 261. That's Rule 251 with manual block provided for reverse direction movements (see the Far Rock and Long Beach lines).
