cars 34700-34755 and 34850-34999, and the drawing shows a single 6'
wide door. Judging by the revision dates on the page I'd say that
the conversion to single door cars happened between 1959 and 1961.
All of the photos that I have of these cars are from the 1960s, so
it's a safe bet that these cars are a "1960s thing".

Ray is essentially correct, though the conversions actually started
somewhat earlier than 1959; the 10/58 ORER shows 19 cars, 34890-34899
(10) and 34990-34999 (9), XM class with 6' wide doors. I have a
photo of 34899, but at the time the photo was taken it had a 4/63
reweigh date.

Does anyone on the list know when IC started this program. I model
circa 1954 and was thinking of changing the Walthers 50' kit into a
single door version and wanted to see if it fit my time frame

Charlie,
The cars were originally built by Mount Vernon in 1929 as IC
162401-162650. In circa 1942 the cars were re# to 40250-40499 as part
of a massive system renumbering program. In April 1951 there were 241
of the original 250 cars in service, and in April 1955 the number was
still high with 233 cars in service. I cannot make any correlation of
IC 34899 to this series of cars.

Ed Hawkins

Hi Charlie,

It looks like this conversion is outside of the scope of this group. My 1954 IC car diagram book doesn't show any of these cars converted into single door cars (34990-34999 with the left door sealed, but left in place), nor does my 1956. My 1964 book DOES: cars 34700-34755 and 34850-34999, and the drawing shows a single 6' wide door. Judging by the revision dates on the page I'd say that the conversion to single door cars happened between 1959 and 1961. All of the photos that I have of these cars are from the 1960s, so it's a safe bet that these cars are a "1960s thing".

And remember: they're all also hide service cars.

Hope this helps!
