Rebuilt AC3 - Ceyhan & Canakkale

[The Rock Doctor]

It's arguably expensive for two knots of speed, but not terribly so.

You're still keen to retain 50% coal-firing at this point?

[TacCovert4]

I wouldn't.  Not at this point.  I mean, if you have oil access, it's just better all around for so many reasons.  If you want to have a coal 'reserve', do 20 percent coal firing, that's enough boilers/fuel to give you a bit of cruising range on coal to get back to an oiler or oil supply using commercial coal stocks.

[Jefgte]

With 25% coal or colonial wood (always useful)

Cost: 7.81$ & 4.1BP
