Realistic Locomotive YouTube Emojis

I’m refreshing my channel’s membership perks and want a small set of custom emojis that look like true-to-life locomotives. The style must stay realistic rather than cartoonish or minimalist, because my audience is made up of rail enthusiasts who notice every bolt and rivet.

Here’s what I need:
• Steam locomotive emojis and diesel locomotive emojis—no electric units this time
• Clean, transparent-background PNGs that meet YouTube’s size limits (I usually upload 48 × 48 px and 72 × 72 px)
• Consistent lighting, colour palette, and line weight so the set feels cohesive
• Final source files (PSD, AI or layered SVG) so I can tweak colours later if needed

Acceptance criteria:
The icons must be clearly recognisable as their respective engine types at 48 px, with crisp edges and no colour fringing. Once delivered, I’ll test them in YouTube Studio; if they scale cleanly and stay legible in the chat preview, the job is done.

If this sounds like your kind of project, let me see a sample of train or vehicle illustration work and we can get rolling.
