ALL CONCERNED:
We are now receiving gravel for road construction at Rosebush. This gravel is coming in two sizes, 10-A small size and 4-A large size.
There are two unloading pits in siding at Rosebush for unloading this gravel. The 10-A small size unloads at east pit and 4-A large size unloads at west pit. These pits are 4 cars lengths apart. When switching these cars up to spot, line up in following manner:
4 cars of 10-a small size, then 4 cars of 4-A large size.
This track will hold 24 cars.
