While filming of the 100th episode of the CBS hit show NCIS Los Angeles is underway the preparations for the next episode are running in full mode as well…

Episode 5 of the fifth season of NCISLA – written by Joe Sachs and directed by Dennis Smith – will be called “The Livelong Day”.

As mentioned in earlier tweets by Producer JP Kousakis and shown in this picture the episode (or at least parts of it) will have something to do with trains (Just CHOO CHOO!!! @JPKouz 8/22)
