Subway

The Sims 3
The Subway is a rabbit hole transportation object that is included in The Sims 3: Late Night expansion pack. The existence of subways was confirmed during a Grant Rodiek "twitterview" on July 29, 2010. Subways will exist as a free, nearly-instantaneous form of transportation, and the player will be able to determine the destination of Sims using the subway. Sims might also be mugged on the subway. It was also confirmed that it can be placed on residential and community lots. It may not be possible to view Sims while they are in it. When your Sim gets robbed (formerly mugged) they may get the "hurt" moodlet. The subway can also be very annoying, your sim may use it to go to a stop that they could get to much quicker just by running.
