Hank the Cow dog

Hello all, I'm doing the steam cargo tutorial in the 1980s, and still very much learning my way around the locomotive, I chose the Hard start and rainy weather, and i was making good progress down the line, but I noticed ran out of water in the tender, or at least i assumed i did, becuase my boiler ran dry and i had all my injectors running. so my question, is it possible to check the water level in the tender? and is it possible to take on water/coal at stations?
