These were long reservoirs of water between the tracks. Most were at least 1000 feet long but I believe more typically that would  be over 2000 feet long. The tender would have a scoop that would lower into the track pan which would collect water and deposit it in the tender while the train kept moving. I read recently that the ideal speed for scooping water was 35-45 mph. Any slower and little water would be gathered. Any fast and the water would slosh off to the sides rather than up through the scoop.</p> <div style="clear:both;"> </div> <p>[/quote]</p> <p>NYC's scoop design allowed scooping water up to 80mph.  April 1945 issue of trains if you can find it.  </p> <p>Discussed here:</p> <p>http://jimquest.com/writ/trains/pans/Track_Pans.pdf</p>
