Warning! Spoilers for Batman #92 below.
Batman has been around long enough that there have been plenty of variations on his vehicle of choice, the Batmobile. However, in the latest issue of his current ongoing series, Batman pulled out an impressive new vehicle that's a pretty fun call-back to the Golden Age of the Caped Crusader.
In James Tynion IV's current Batman run, he's had some fun with the gadgets and vehicles used by the Dark Knight. He's introduced a pocket-size Batmobile maker called Echo, as well as a new gadget called Shadowcaster, a new tracker that can keep tabs on his opponent's movements. Tynion IV has introduced a new vehicle Batman that's not only a callback to the Batman of the '50s, but the new ride puts the Batmobile to shame.
This week's Batman #92 by Tynion IV, Guillem March, Tomeu Morey, and Clayton Cowles, see the World's Greatest Detective reluctantly teaming up with Deathstroke in order to stop the Riddler. Stuck in one of the villain's games, Batman and Slade attempt to find the Riddler so they could take him out before his game's cause more damage and chaos across Gotham. The duo head down into the Gotham subway, when Batman calls for his Bat-Train. Deathstroke is totally shocked, telling Batman "you're kidding me. A Bat-Train?"
With a practically unlimited amount of resources, it shouldn't all that surprising that Batman has a Bat-Train capable of driving him through Gotham's underbelly. The Bat-Train is actually a call-back to the Golden Age of Batman. The original Bat-Train first appeared in Batman #95 by Bill Finger and Sheldon Moldoff. That version of the Bat-Train was a steam-engine locomotive and featured a giant Batman mask on the front. It's one of the siller things that has ever been featured in the pages of Batman, but it's still quite iconic.
The newer Bat-Train works as planned, quickly getting Batman and Deathstroke to the Riddler's hideout. Batman subdues the Riddler with a tranquilizer, before using an even more powerful tranquilizer to take down Deathstroke for a couple hours. The Batman/Deathstroke team-up was an unexpectedly delightful mini-arc with Slade's reaction to the Bat-Train being hilarious. It's safe to assume Deathstroke didn't foresee a Bat-Train being a part of the duo's takedown of the Riddler. He's Batman so of course he's got a Bat-Train. Why? Because he's the 'God Damn Batman," that's why.
