 # railroad_paraphernalia
-This mod introduces railroad equipment from the 1986 signaling manual for the USSR railways.
+This mod introduces railroad equipment, mostly from the 1986 signaling manual for the USSR railways.
+
+##Point levers
+An accessory that makes a railroad switch look professional. Also helps
+users of advtrains without train_operator privilege to operate switches in style.
+
+With black&white arrow:
+```
+{'dye:black', 'dye:white', 'dye:black'},
+{'', 'default:stick', 'default:stick'},
+{'default:steel_ingot', 'default:steel_ingot', 'default:steel_ingot'},
+```
+
+With blue&yellow signal lamp:
+```
+{'dye:grey', 'dye:yellow', 'dye:white'},
+{'', 'default:stick', 'default:stick'},
+{'default:steel_ingot', 'default:steel_ingot', 'default:steel_ingot'},
+```
+
+While it should be a light source, the details of the model cannot be seen even when it
+emits the minimal amount of light.
+
+##Track Blocker
+Prevents a tran from passing a track segment by placing a "block" in its
+way. Isn't synced with advtrains ndb, so works only with manned trains for now.
+```
+{'dye:white', 'dye:black', 'dye:white'},
+{'', 'default:stick', ''},
+{'dye:red', 'default:steel_ingot', 'default:steel_ingot'},
+```
+
+##Shunting signal
+A small signal for shunting operations. Blue = shunting prohibited, white = shutung allowed.
+```
+{'', 'dye:white', ''},
+{'', 'dye:blue', ''},
+{'', 'default:stone', ''},
+```
+
+##Delimiting post: 
+It is placed near switches to show the point past which the locomotive may
+not be parked, since it would collide with the train on the other track.
+```
+{'', 'dye:black', ''},
+{'', 'dye:white', ''},
+{'', 'default:stone', ''},
+```
