Sentai 2014 Confirmed: Ressha Sentai Tokkyuger

From Henshin Justice:

It’s now confirmed through the trademark databases! The next Super Sentai for 2014 is called, Ressha Sentai Tokkyuger (烈車戦隊トッキュウジャー)!
The title Ressha is a pun on the Japanese word ressha, which means train using the kanji characters for 烈車 vehement car instead of the usual 列車 line car. While Tokkyu means limited express train. Our new Super Sentai will most likely be train-based!

Let the speculation begin!
