I've seen several pictures of steam engines with a tank car behind the tender and hooked up for use as extra water. What tank cars are available that would be of the right type to use in such a manner? The few I've seen seem to have multiple fittings on the tank turret, something I haven't seen in the photos. Would I have to redo the turret to have a single inlet or should I just find a tank car that was used in a specific type of service and go from there?
TIA
