train position
A sex position involving at least three participants. The participants must have their bodies close together, all facing the same direction. It can be performed standing, laying down, or sitting. Gender and penetration do not matter. It resembles the linked boxcars of a train.
If a participant is visibly being penetrated by one participant, and visibly penetrating another participant, they are known as a "lucky_pierre".
This position should technically always be a rear-entry position, as oral only variants fall under either daisy_chain, or daisy_train. A train may contain oral components as long as one of the participants is in a penetrative compatible posture. It may still be possible to have a train that has side-entry components, and not have a true rear-entry orientation. These types of positions usually do not fit well under either train, or sandwich, but should fall under lucky pierre.
Editor's notes
This tag still contains remnants from when it used to be applicable to penetration that flows in the same direction, and the orientation of the partners wasn't important, a distinction that now belongs to the lucky pierre tag. This tag needs to have the lucky pierre tag added where it is missing, and examples that go into the oral end of a spitroast moved to mixed_sandwich_position instead.
Examples
M/M/M train position standing up. The black dog is a lucky_pierre.
Train position with eight characters
Train position with ambiguous penetration
Train position featuring an ass_stack
Train position with oral components (unlike sandwich position, which excludes spitroast related postures, the train position allows these postures)
Not to be confused with
Sandwich position
The sandwich position features a participant facing in the opposite direction (so the the outmost members form a "sandwich" facing inwards).
Note: If there are more than three participants, the position could be both a sandwich_position and a train_position.
Daisy chain
A daisy chain is a series of characters all performing oral on each other in a looped sequence.
Daisy train
A daisy train is a series of characters performing oral on each other in a non-looped sequence.
