Sausage train 

A group of males all walking together with each other, usually in single file.

When I saw six people entering the restaurant and going towards their table I didn't see one woman; it was a sausage train.

Sausage train 

When several dudes are "connected" as if in a train.

That's not a human centipede, that's a sausage train.

Train Sausage 

The remains of a living thing after being hit by a train. The meat remains left behind by a train can resemble ground sausage: therefore, it is called train sausage.

When traversing a zombie-filled subway, stay off the tracks to avoid being train sausage'd.

While travelling the Tundra Express, always mind your surroundings. Trains love to sneak up on you and turn you into train sausage.
