Re: Pacemaker boxcar usage off-line of NYC

Guy Wilber

<<The reason I asked, a couple of nights back, about the exact stencilling requirements for interchange, had to do with the Sisk photo referenced earlier in this thread. The car has reporting marks, load limit, light weight, and nothing else: no capacity, no dimensional data, no dates. The picture was taken, the caption says, in 1948 in Kansas City. The NYC doesn't go to KC, so the car is off line. >>

All interchanged cars were to meet the stenciling requirements within Interchange Rules 3, 30, and 86. All cars were also subject to the requirements of the Operating-Transportation Department of the ARA and AAR (post 1934). This includes all provisions within the Car Service Rules and The Standards of The Lettering and Markings of Cars within the Manual of Standard and Recommended Practice of the Association often referenced within the Interchange Rules.

The following entries are from the 1956 Interchange Rules. Though renumbered (several times), the first three paragraphs of Rule 3 are essentially the same as from 1933 forward. Paragraph 7 was added in 1953 with an effective date of January 1, 1955, and Paragraph 8 was added in 1955. Rules 30 and 86 are as they were from the late 1920s with some modifications throughout the years. If you have specific time period questions regarding modifications they can be answered.

INTERCHANGE RULES (Effective January 1, 1956):

Rule 3, Section (s), Paragraph (4) Stenciling: Date built new, month and year, or badge plate giving this information, required on all cars. Date rebuilt, in addition to date built new, month and year or badge plate giving this information, required on all cars rebuilt on or after July 1, 1928. From owners. In event tank and underframe of tank car are built at different times each must bear distinctive dates, the dates on underframe to be date underframe (including trucks) was built new.

Rule 3, Section (s), Paragraph (5) Stenciling: Light weight and capacity in pounds, as provided in Rules 30 and 86, required on all cars. In Interchange. Tank cars and live poultry cars shall be reweighed and remarked by the owners or their authorized representatives.

Rule 3, Section (s), Paragraph (6) Stenciling: Load limit markings, as provided in Rule 30, required all cars except tank cars and live poultry cars. In Interchange.

Rule 3, Section (s), Paragraph (7) Stenciling: Car initials and numbers required on one side of each truck bolster. From Owners.

Rule 3, Section (s), Paragraph (8) Stenciling: All car initials and numbers per pages L-37 through L-39-D of Manual of Standard and Recommended Practice must be legible. From Owners.

Rule 30, Section (F)--Stenciling.

Paragraph (1) Should be in accordance with AAR Standards for Marking and Lettering of Cars.

Paragraph (2) Station symbol and date (month and year) must be stenciled on cars when new and each time re-weighed and re-stenciled. On new cars the word "new" may be substituted for station symbol.

Paragraph (3) When cars are re-stenciled after re-weighing, all old stenciling to be renewed must be obliterated with quick drying paint. It will be necessary only to renew all light-weight numerals, station symbol, date (month and year), and load limit numerals except as provided in Paragraph 6, section (F). The capacity numeral and letters "CAPY", "LD LMT", and "LT WT", when indistinct, must be renewed. light weight stenciling on ends of cars is not permitted and when shown must be obliterated.

Paragraph (4) The light weight stenciling shall be the multiple of 100 lbs. nearest the scale weight, except that when the scale weight indicates an even 50 lbs. the lower multiple shall be used.

Paragraph (5) The LOAD LIMIT, which is the difference between the light weight and the maximum weight on rail, as shown in table in AAR Interchange Rule 86, shall be initially stenciled on all cars (except tank and live poultry cars) by the car owner. The "load limit" is the permissible weight of the lading, including weight of temporary fixtures, also brine and ice in refrigerator cars. Stenciled load limit must not be more than nominal capacity.

Paragraph (6) When account structural limitations or other reasons, car owner has reduced the load limit of a car, a star symbol (*), the size of which shall conform to standard lettering for "LD LMT" shall be placed at immediate left of words "LD LMT", and when thus designated the load limit shall be changed only be the car owner.

Paragraph (7) The NOMINAL CAPACITY in multiples of 1,000 pounds, shall be initially stenciled on car by car owner and must not exceed the stenciled load limit.

Paragraph (8) The CUBIC CAPACITY shall be initially stenciled on cars, by car owner, except that such markings are not required on flat, tank, and live poultry cars.

Rule 86, Section (a), Paragraph (4) All cars to have their light weight and capacity in pounds stenciled on them, as per Section (s), Paragraph (5), Rule 3. Load limit markings are also required on all cars, except tank cars and live poultry cars, as provided in Rule 30.

<<The car-service rules in the 1/43 and 1/53 ORERs state what's supposed to be stencilled, but don't explicitly say what's required for interchange. I don't have a copy of the interchange rules; the group archives yield several comments that "weights" were to be stencilled, but I haven't found a firm statement as to *which* weights. I seek wisdom: does the car in Sisk's photo conform to the requirements, or not?>>

The NYC car in question does not conform to the provisions of the Interchange Rules.
