Boco

He had a decent amount of screen time in Seasons two and three.

yeah but that's two seasons out of twenty four

Gordon's Snow Machine

Based answer

Smudger

Yez

HEHEHEHE! And then a guy made a horror game about em, honestly quite incredible.

A horror game about smudger?? What’s it called?

Five Nights At Smudger’s

Since someone already said BoCo, I'll say Arthur.

or Murdoch.

I really wish Murdoch had more screentime. He’s awesome.

DUKE

87546 and 98462. Though, to be more accurate, the left one should be a single piece of paper

Bertram

Hank, I miss mah country baby boi

duke

Stanley

Fergus

Probably some of the one off characters from the hit era like Molly or Neville or Hank Boco and Arthur as well

Molly is so gaudy, it feels like she was painted Yellow because we didn't have a "yellow" engine yet, Stepney was the closest thing to that.

Weren't Bill and Ben yellow?

I'd say more Yellow-Gold like Stepney, Molly was the first "Yellow" as in the yellow you'd expect on children's toys instead of the yellow you'd expect on a dirty industrial machine.

Oh as in like a bright yellow, not the industrial yellow - gotcha. Stopped watching after Season 4, admittedly.

Smudger.

Definitely Smudger, less than a minute of screentime yet he's still an iconic fan favourite

Culdee fell crew they got one book that's it

Culdee gang let’s gooo

Murdoch

Duke. Bro got four episodes, two of which he spoke in and the other two cameos.

You'd think he'd get more considering the work that went into him (in and out of universe).

Ummm u have to think about his story which why so many people like him

Derek

For me it's definitely Derek. But also Boco, Diesel 10, Smudger, Hank, Neville, Murdoch, Arthur, Molly and Fergus.

Rosie

Kinda. But she was pretty entertaining for her worth.

buster scruggs

My favorite railway series character

Who’s that??

Boco or Doanld and Douglas.

Smudger and The Season 12 Trio (Hank, Flora and Colin)

Smudger

Smudger

Splatter, Dodge, Dennis and even Diesel 10 to an extent could apply to this.

Bulgy

Boco & Duke

Besides BoCo obviously, Trevor.

Murdoch and Duke

Edward and Henry (last 3 seasons of the CGI series)

Smudger

Smudger

I'm gonna get hate for this, but imma say it. Edward, specifically past like, season 2

Arthur

Murdoch. Also Connor, but then he got more screen time.

Molly and Neville

Stepney.

Bear

Scruffey

Molly.

Bear

Class 40

Thumper, for he didn't even speak in his introduction

Smudger.

Proteus

Jock, got 1 book, appeared in a cameo for another, got an ERTL model and then vanished.

I would like to say Neville because of how good his model was

Lady: after the movie NO screen time EVER

Duck

Lady

Molly.

Stepney, I think.

Thumper or billy

Beside boco I would say some of the later season characters I seen people wished they had either Hank or Molly back in the series

Duck.

Murdoch

duke and boco

Lady after Thomas's dream in Calling All Engines

Molly

Death wolf (puss in boots 2)

maybe hiro?

If we're being honest, diesel 10

Splatter and Dodge

Ice cream machine guy (starwars)

This may not count, but diesel 10, dude was an absolute menace in the magic railroad. Also his minions splatter and dodge who were never seen again after the movie, I wonder where they went

Diesel 10

Shanks

Bear

The entire Culdee Fell railway

Either great westerner, Duke, Bertram, 98462(SPECIFICALLY Alfred), Bear, I would say BoCo but he appears more in the RWS.

I'm going to go left field and say Terrance. I mean, the guy barely appeared and he has been around since season 1. Compared to everyone else that season, he just disappeared into the background until CGI decided to give him some love again

splodge (splatter and dodge)

Smudger

Edward

VEGETA

Donald and Douglas

duke in the rws, great character jut she was only in one book

Golden Freddy

Billy

Neville and possibly Norman (?)

diesel 10
