    I'm not 100% sure if this is the proper place to ask (but seeing as how the Talyllyn has a gauge "greater than 15" and below standard gauge", then why not?). But I just wanted to ask some questions about No. 4 "Edward Thomas". Does anyone know any reliable information regarding the fuel and water capacity of No. 4, or where I could find that information? Also, does anyone happen to know what the bunker on the driver's/right hand side is for?

    It doesn't appear to be used for coal. Sand maybe?

    I assume the weight is in long tons, and the water capacity is in Imperial gallons and not US gallons?

    Ah - this explains a PM I had earlier today - not from 7p, mind (I only popped in to see what was going on in the Teifi thread).

    If you look at pictures of 4047, on the Corris the right hand bunker was generally used to carry pokers, fireirons and a bucket of sand: remember that there was no footplating. Photographs of the engine without the superstructure and on a transfer wagon indicate that the bunker had a solid base, with no discernable holes.

    Today, the bunker is used to hold the spare oil bottles, rags, a couple of Thomas the Tank engine flags and a sandwich wrapper, as well as the equalising reservoirs for the single-pipe Westo.

    Ah, I see! Thank you, very much! I could never figure out what it was for, and it was bothering me.

    160 would seem about right. Although I wouldn't be surprised if it was 180 or even somewhere close to 200. But that's just me.
