Re: NG tender capacities

I don't know about current capacities; things sometimes change with rebuilds and tenders are one of the items most frequently changed.

The D&RG class 45½ and class 47 ten-wheelers were delivered with 2000 gallon tanks. The class 60 locomotives mostly came with 2500 gallon tanks. The first few had 1400 or 1500 gallon tanks, but that's not representative of the majority of the class and certainly not the specific locomotive you mention. All of the class 70 locomotives were delivered with 2500 gallon tanks as well. The 2000 and 2500 gallon tenders were larger than the default Baldwin sizes for those classes of locomotives--probably due to longer runs on the D&RG's extensive system. The EBT #7 2-8-0 built to the same plans as the D&RG class 70 locomotives had a 1600 gallon tender tank, as did the ET&WNC 2-8-0's built to similar plans as the D&RG class 60 engines.

E&P 4 was delivered with a 1000 gallon tender capacity; that was the standard size for that model at the time. Some sent to Brazil had small 750 gallon 4-wheel tenders. "Glenbrook" had a 1200 gallon tank; the similar-size "Emma Nevada" has a 1400 gallon tender. As a general rule of thumb, tender sizes tended to increase over time. E&P 4 and its sibling locomotives built during the mid 1870's had 1000 gallon tenders standard; by the mid 1880's locomotives of the same class were routinely being delivered with 1400 and 1600 gallon tenders, and sometimes larger.
