In 1903-4 3,300 more fishbelly side sill cars were installed of modified design, numbered 16000-16999 and 32000-34299; they differed in side sills, end sills, door track and underbody. The 1903-4 cars were renumbered 71000-729299 and 86000-86999 in 1908 and given safety appliance is 1915. Cars built by Standard Steel received 6-rung ladders on the sides and ends and reinforced doors. When given safety appliances the lettering scheme was changed to reflect both the new NH reporting marks and the MCB appliance and size standards. Another general rebuilding took place in 1925-6. Only slight changes were made at this time. However, 1925 cars received a tourist slogan on the door. In 1927-28 the remaining cars were rebuilt as single sheathed cars and renumbered into the 170000-170999 series. When given cast sideframe trucks beginning in 1937 cars were renumbered to the 70000-70999 series. The cars ran ininterchange to about 1950 but many cars were shifted to MOW for tax purposes were they continued to run in captive service somewhat later. Further cars were converted to work, wire and tower service where they ran into the early 1960s. PLEASE SEE OUR SS BOX CAR SECTION FOR OTHER #10500 SERIES KITS.
