One of more vehicles are higher than is allowed to the loading gauge. Some track restrictions do apply. (lower bridges, platform tracks). OG Trains Class A are NOT announced particularly by neighbouring dispatchers, neither has the dispatchers to announce them to the neighbours.
Class B
These are trains that just go over the loading gauge in WIDTH but to NOT reach into the neighbour track loading gauge. A Class B can pass a Class B OG train. OG Class B trains are NOT announced to the neighbours.
Class C
These are trains that so wide in loading gauge that If they pass a Class B OG train, it will collide. If it meets a Class A or other train than C or D, nothing will happen. Class C trains are announced by TELEPHONE (in addition to ZNP 801?)
Class D
These trains are so wide that ANY neighbour track MUST be clear of vehicles. Some class D trains have special cars that can shift the load sideways on certain spots (bridges, signals) and/or stop/go really slow for a while prepping for/passing the object next to the track. Class D trains come with extensive paperwork. Class D trains are announced by TELEPHONE (in addition to ZNP801)
Graphical visualization of out of gauge loads
The load exceeds the track gauge upwards or downwards.
Basically does not affect the adjacent track.
The load reaches at maximum up to the middle of the space between two adjacent tracks.
Allows passing on the adjacent tracks of:
Trains with normal loads
Out of gauge train Class A (Lü Anton)
Out of gauge train Class B (Lü Berta)
The load reaches over the middle of the space between two adjacent tracks.
Allows passing on the adjacent tracks of:
trains with normal loads
Out of gauge train Class A (Lü Anton)
The load reaches that far into gauge of the adjacent track, that no train movements are possible on the adjacent track.
