Why did they have such small fuel bunkers?  Or were the fuel bunkers on the Shay and Climax about the sane.  Obviously I'm referring to the real world.

Most times two water stops to fuel stop.  In general plan was approximately on coal fired 14 tons coal to 10000 gallons of water.  Oil has less waste than coal so get away with less amount to water.
Logging mallets while a bit more 'mainline than geared still where not traveling very long distances.  The traction that the weight of the water provided more important.

The Uintah articulated ( not a mallet) also had a relatively small coal bunker though they got extended compared to the water tanks.  The coal the Uintah used was pretty dirty though.  Again not traveling very long distance from Atchee to the mines was only about 25 track miles, it was the 7.5% grade that was the killer.

Some logging lines did add tenders sometimes as lines got longer.
