I went through 24 years of Lionel catalogs helping build the CCMF database. Here are some thoughts on these years.
Lionel from early on did high quality catalogs. There were errors, but overall the catalogs were pleasing and aimed at adults that had the money. When I was 8 I had a 1964 catalog. It was soon worn out.
Lionel was very much an engineering company is the feel I have. Science sets looked really good, but relatively expensive for the time. Overdone is my thought when I went through the Science part of the catalog.
Military, missile, space and science sets of the Late 1950's and early 1960's followed the "Sputnik" reaction the whole United States was going through.
Making the 2625-28 Madison series cars was expensive. Method of manufacture was costly. Bakelite plastic was a thermoset which was slower to mold. Spruces and trimmings were waste with dumping costs. Switch to thermoplastics allowed re-use of sprues and flash in the melt reducing waste costs. It was faster, cheaper and flexible.
In 1961 Lionel tried to jump on the toy car racing arena. They converted HO system into a race car set on HO track.... How do you pass? It was a double loop with 2 crossings. 2 chances to crash at the track crossing at the top or bottom of the loop. A nice engineering answer, but not a market answer. They didn't see this failure coming? By 1963 they had acquired or built a race set.
O27 sets had transformers, "O" sets did not. Probably to keep price shock down. O27 had the beginner sets. There were high end O27 also. The transformers were matched very well to the power needs of the set. The led to many transformers increasing inventory and tracking costs.
O and Super O sets it was probably best to have the dealer help with transformer choice. O and Super O sets had more lights and accessories.
Transformers wattage ratings in sets increased for lights 10W, 10W more for smoke, 15W more for whistle and 20-30W for lighted passenger systems. 90W transformers For most passenger sets.
Coil couplers were expensive. When the switch came it dropped set prices up to 10%. Also maintaining 1 coil on a track is easier than maintaining 2 for each car.
Magnetic coupler conversion on O27 was quick. On "O" sets it took a couple of years. Higher end sets may have absorbed the cost/surplus better.
Listing the train length and track size, down to 1/16 until 1954. But inconsistent, the same track may change up to 3/8" from year to year.
X at end usually meant it came in a set. But X used for other things also.
Lionel used part number suffixes, -xxx to track variations in Railroad marking and manufacturing design. Catalogs did no appear to consistently list -xxx in the item. I did not see a consistent logic when creating a new part number 6219 vs. Variation number 6119-xxx. In many cases not bothering to track the difference.
Low cost hoppers, gondolas and caboose led to many variants in color, molds and on. I think most charts on variants are nice, but I don't know if we can ever be sure on these low cost items. Variant A, B C etc. was never in the catalogs, they have been built by the collector community.
Most O27 passenger cars and Caboose were not lighted. Most all "O" passenger cars and Caboose were lighted.
Low cost O27 locos and rolling stock were not usually offered for separate sale in the catalogs.
The electronic set was expensive even for Lionel. By my calculations the core components almost doubled in price from 1947 to 1948. The base set was $75 in 1947. $60 worth of accessories were added to the set in 1948. The core components in 1948 calculate as $130 of the retail $199 price. I wonder if the 1 year jump was driven by component supply chain problems.
If the 1948 illustrated "Black Bonnet" was an error but a desired look today. The catalog was corrected the next year to reflect the correct silver color.
The 622/6220 were the magne-traction prototypes in 1949. The magne-traction didn't do well the first year. The next year magnets moved closer to the wheels and proliferated through the product line in 1950 and on.
Submarine cars had 2 types. Assembled sub or the sub came in a kit. 7.95 for the flat car & kit version vs. 8.95 if for the flat car and assembled sub version.
For high end sets in the 1940's and early 1950's the xx.95 pricing was abandoned. 75.00, 85.00 etc. Was it a bragging point for the high end sets?
Few customized instruction books. General purpose. Printing was not as easy to prepare as today.
New rolling stock each year, including locomotives, went from 1946 count of 44 each year until the high point of 75 new offerings in 1959. Then went down until 1963 with a count of 38. 1964 a big drop down to 22. 1965-69 only added 25 more that were not customs for clubs. In the 1960's size and accuracy of the catalogs fell. Many errors related to -xxx variants. Lack of proof reading or organizational errors or both is unclear. 1967 did not even have a catalog. The 1968 and 1969 catalogs were small.
Locomotives, dummy locomotives and power units were around 259 with rolling stock including tenders around 510. About a 1 to 2 loco to rolling stock ratio. There is a reason locos seem plentiful.
Locomotives were the focus in catalogs. In 1955-57 sets were not listed in the Catalog and additional focus was on the locomotives. Set listings returned in 1958 Listing of track oval size was abandoned.
There were about 520 cataloged sets in the Post War era. About half were O27. Higher end were the O or Super O sets.
1961, dropped W (Whistle) & S (Smoke) from set ID's.
Locos were the major cost in the sets. The initial F3 Diesels had Horizontal "growler" motors. Converting to a vertical motor in the following years reduced consumer cost by $10 for a dual engine Diesel. This was 10-20% of the set cost. A major cost change.
Some loco's were used in both O27 and O/Super O sets.
Tenders
were not specifically mentioned in the xxxLT loco/tender set listings,
only a whistling note. Tender matching had to be deduced from sets and
pictures.
Many cheap slope back tenders were fundamentally identical.
Super O Track was nice, but listed for 2 times the price of the regular O track. 1964 back to O track. Super O last shown with the top 773 Loco set in 1964. It was still shown for separate sale thru 1966.
Only 1 control track for 2 or more dumping cars. No set had more than 1 control track. Some Operating cars came with their own clips for activation. Operating Milk, Cattle and Horse cars and others.
HO sets were not much cheaper than O gauge sets. Lionel may not have scaled down well. HO appears to be just copies of their O gauge sets.
Chances are rare, but if you ever find the original 1946 smoke pellets, leave them sealed, don't try to use them. They act more like sparklers in 1947 and newer smoke units and burn them up. Probably classified as a fire hazard today.
Catalog info vs. what a lot of others say, does it all agree? Maybe not.
What would I have done different? Added at least 4 more straight track in sets. Why? lots of track makes it look like it needs more cars. A little more attention to inventory and business also.
See the CCMF catalog. All the postwar locos, rolling stock and sets have been entered by year. Much easier than searching 24 years of catalogs.
