How to Dragon your Train! The Krea 2 based follow up to the version I did for SD 1.5 years ago. And now it actually works! What is a dragontrain? The dragontrain concept is a real life train that has been drawn as a dragon, using the same colors and markings. The train has been transformed into a dragon or other creature. A dragontrain always has a drawing, and then a reference photo in the corner. The trigger word is <code>dragontrain</code> . Use this somewhere in your prompt to get an effect. But it requires a long prompt to work like the example images. You need to give it a detailed description or the dragontraining with reference just won't happen. This model is hard to prompt, but this gives it a lot of flexibility. Check the example images for good prompts. It is possible to write them by hand, but it is a difficult process to target exactly what the model expects, if you're going for the intended usage. This model has many unintended uses. It can make super cool robot dragons and other robotic creatures. Here's what I use to have gemma 4 write new prompts:<pre><code>What is a dragontrain?

Original dragontrain prompts:
A poster illustration of a dragontrain, a muscular male anthro hybrid that is a living machine, combining a white high-speed train with a serpentine dragon. The creature has a white body with red graphic markings and tattoos across its chest, back, and arms, mirroring the livery of the Kereta Cepat Indonesia China. It is legless and serpentine, with a long, winding tail. Seen from a rear view, the creature twists its muscular torso, opening its mouth to reveal fangs and a long tongue that it uses to lick its own muscular bicep. The top of the poster features a photograph of the real high-speed train traveling on a bridge over a green landscape.

A reference image featuring a dragontrain based on an Italian FS Class ETR 300 Settebello electric railcar. In the top left corner is a photo of the original vehicle, a grey train with green stripes and red accents on the lower front, parked on railway tracks. The main focus of the image is a digital illustration of the resulting dragontrain head, shown in profile. The creature is a hybrid living machine with a multicolored body consisting of grey scales, green stripes along its neck and cheek, and a red lower jaw and belly. It features a small black horn on its nose, an open mouth revealing white teeth, and a dorsal ridge of grey spikes along its head and neck. The eyes have grey sclera and dark pupils. The background is a simple, painterly blend of blue and tan.

This reference image features a dragontrain, a humanoid hybrid creature designed as a living machine based on a diesel-electric locomotive. The creature has a dark blue body with gold markings and a blocky snout. It has an underbite showing sharp white teeth and a grin. Its eyes feature black sclera with square yellow pupils. On its head are two large, curved black horns adorned with gold studs, and blue ears with white inner ears. The creature wears gold jewelry, including a thick gold chain necklace with a gold shield pendant featuring a mountain logo, as well as gold piercings in the nose, eyebrow, and gauged ears. Gold and white spikes run along its neck and back. The text "8011" is written on its head, and "MOUNTAINEER" is written on its neck. In the background on the left is a photo of the real-life Rocky Mountaineer EMD GP40 locomotive, numbered "8011", sitting on train tracks against a backdrop of snowy mountains. The creature is positioned on the right against a simple tan background.
