You'll find them in the config.txt file for the tender (or the loco if it's a tank loco). Look for the queues container. The water capacity is set by the size tag in the load-water queue and fuel cap by the size tag in the load-coal queue.
Size is total volume of the queue specified in litres. Density used for water is 1kg/ltr. For coal the built-in Auran coal product that's used by most configs for locomotive coal has a density of 0.86 kg/ltr.
Water capacity of most tenders is usually given in volume measure so it's a straight forward conversion to litres. For coal it's usually given in weight or mass so you have to convert to volume based on density given above.
You can also use the actual volume of the coal bin if you know it. Be warned though that Auran uses litres as the units it's programmed to transfer amounts of product in and out of the queues but in the steam-engine config the fuel transfered from tender to fire box is specified in kgs/shovel. Unfortunately they hard coded the density used to make the conversion (0.86 kg/ltr) so working with something other than their std coal is a pain if you want to simulate accurate differences between types of fuel. They also work only with integer values of litres when transfering a product in and out of a queue which also complicates things if trying to be too accurate.
