Running a train

Contrary to popular belief, this sexual act has an alternate meaning in the community of those with a fetish for model trains.

There are many ways to “run a train” on a sexual partner, however some of the most popular in the community are:
- Starting the locomotive at the base of the station master’s phallus and establishing with the conductor whether this scheduled transit is going towards the tunnel entrance or secondary option the shallow valley.
- “The tunnel ” will require more preparation to the track work. It is often met with scheduled exits on the same timeline.

Oi bruv you should’ve helped run that train, you’d make a hot conductor. I bet you’d be more efficient at running a train than the city council.
