Puffing Tom

The Puffing Tom is Tom's finest and most powerful Sea Train. Puffing Tom was built during Tom's original ten year hiatus from government persecution, with significant improvements added over the Rocket Man.

Design
Puffing Tom's design was based on historical 19th century. The color scheme was green and red with orange and yellow for extra decoration. In addition to its Engine and Coal car Puffing Tom carried several passenger cars. During its trip to Enies Lobby several of these were destroyed by the Straw hats or the Franky Family. The Puffing Tom also had cargo cars which were shown only briefly.

Events on the Sea train
After events in Water 7 Sanji discovered Robin was on board the Puffing Tom. Sanji stowed away after leaving a note/love letter to Nami about his plan. After the Train was a short distance from Water 7, Sanji entered the Tom from his hiding place on the stern car. He quickly subdued the soldiers in the Rear car including Jerry of CP6. In the following car he freed Usopp and Franky. After luring T-Bone and his men into the two rear cars he cut them loose. Moving along with Franky and the disguised Usopp they encounter CP7's Wanze. Leaving Sanji to deal with Wanze, Usopp and Franky split up. While Usopp used his octoshoes to reach Robin, Franky became involved in a fight with Nero. All three people accomplish their task simultaneously and end up in CP9's car. A desperate escape ensues with the three of them and Robin in the three rear cars. However Blueno's Devil Fruit powers and Robins unwillingness to be saved thwarted the escape and lead to the recapture of Robin and Franky. The Puffing Tom and its remaining cars continued to Enies Lobby.

Escape from Enies Lobby
As the Buster call razed the government stronghold the Franky Family, Galley-La foremen, and the giants commandeered the Puffing Tom and escaped to Water 7.
