|"Going up- Engine of Wishes, T-Line!"|
|―T-Line's role call[src]|
Engine T-line (炎神ティライン Enjin Tirain) is a hybrid of a Tyrannosaurus Rex and a freight liner. He is split into two items when in storage, an Engine Cast and the number 11 Engine Soul. He serves as Kyouretsu-O's right leg and Engine-O G12's right arm. He forms the middle car in the Ancient Engine line.
T-line is primitive and his brutality is directed towards the Machine Family. He can also jump up and bite foes in tandem with K-Line. Being of primitive origins, he cannot talk but only speak in Tyrannosaurus roars, which can be understood by others.

T-line was part of a group of Tyrannosaurus Mecha manifestations which appeared around the Gabutyra head of Kyoryuzin as its Miracle Combination prepared the Zyuden Brave Strike End Rider Kick attack which destroyed Demon King Psycho.
- His title as the "Engine of Wishes" is a reference to the fastest publicly available train run on the Tokyo/Osaka/Fukuoka line.
