It doesn't matter because the fireman would have to break up some of the coal anyway

Yes you are because it doesn't even have brass handrails!

If it fits through the door then it goes in, on the WHR some of the lumps are like house bricks, I tend to not bother with the shovel when they are this big.

There's a few differences between an A4 at 100mph and a Penrhyn Lady at 25mph.

Burn longer, yes. More efficient, probably not- you'll probably actually get less heat energy out of an over large chunk even over the long period of time it burns for than you would over a similar mass of smaller chunks- obviously there will be a point where the small chunks become too small and it swaps around.

Not that it's even slightly relevant on something as patently inefficient as a coal fired steam loco of course!

I'd have thought a similar mass of smaller sized bits would burn better, as there's more surface area for the oxygen to get to for it to burn.

Yup, thats one of the mods im thinking of doing myself, along with glazed specical plates. Going to have a look a the real things floor first though to get it as accurate as possible.

As a general rule of thumb on road steam, if it wont go in, wedge it and give it a boot. if it still wont go in its too big..

You cant, feck about breaking up coal on the road, not when your trying to keep a water level, fire, drive and more often than not steer aswell

That's just one of the reasons I'd have a railway engine any day.

Only really convenient if there's a railway outside your front door though ;)

It's funny, in model form I'd much rather have a railway loco than a road loco. But in full size it's the opposite, although I'm more interested in railways a road steamer appeals much more.

Not a roller though, I've driven (steered really) one years ago, it's too much like hard work :lol:

the bigger the lum the better as you dont have to put as much on

big lumps go on your back end and smaller ones down the front on standard gauge loco's

will, we where rolling snowmen over with our roller on sunday

See above... technically you'd actually have to put slightly more on in terms off mass as it'd burn less efficiently.
