675 K-4 Pacific

Production:  1947 - 1949 & 1952

History
The 675 steam engine was classified by Lionel as a K4 Pacific steam-type engine and was designed off the real life Pennsylvania K4 Pacific locomotive. The wheel arrangement on the real K4 was a 4-6-2 as opposed to Lionel's initial 2-6-2 wheel arrangement. Back in the late 1940's, this steam engine was a mid-sized locomotive within Lionel's motive power roster and was considered a quality locomotive.

Lionel's 675 is the same locomotive as the 2025 locomotive -- with the exception of the number on the cab. The 675 was classified as an O gauge engine while the 2025 was sold as an 027 gauge steamer. Lastly, the 675 does share its boiler casting with the 2035 steamer, however the internal workings are different.

Features
The 675 steam locomotive had two independent production runs, but numerous variations throughout the entire production cycle. The first production run was from 1947 through 1949 while the second was a single-year run in 1952. Although each production run carried the same cab number, in most cases parts are not interchangeable between the early and late version.

• The first production run started in 1947 and ran through 1949 with several minor variations:
• The earliest run in 1947 consisted of a 2-6-2 wheel arrangement with detailed driving wheel hardware, three position E-unit, smoke, Baldwin disk drive wheels, die-cast trailing truck, ornamental bell and headlight.
• Boiler Number: The number on the keystone was either 675 or 5690. It is generally believed the 675 number appeared on 1947 production while the 5690 appearing on 1948, 1949 and 1952 production.
• Smokestack: For 1947, the smokestack was unpainted aluminum. For 1948, 1949 and 1952, the smokestack was modified from a separate aluminum piece to a black-painted stack.
• Simulated Knuckle Coupler: Another minor mold modification was the inclusion of a simulated knuckle couple cast into the cowcatcher. For 1947 there was no simulated knuckle coupler cast into the cowcatcher, while the 1948, 1949 and 1952 variations did include a small simulated knuckle cast into the cowcatcher.
• Tender: Initially the whistling tender was numbered 2466WX, however sometime in late 1947 or early 1948 it changed to 6466WX. The number change corresponded to a change from coil couplers on the 2466WX to magnetic couplers on the 6466WX.
• The final 675 run was in 1952. Externally, the 1952 model looks very similar to the earlier models. Internally, there are numerous differences. The 1952 model has a 2-6-4 wheel arrangement with detailed driving-wheel hardware, three-position E-unit, smoke, relatively plain spoked drive wheels, sheet metal trailing truck plus ornamental bell and headlight. The number on the keystone of the boiler front was always 5690 while the tender was always the 2046W whistling tender.

Additional Detail, Photos & Box Information
The length of a 675 and 2466WX or 6466WX tender is approximately 18 1/2" long (cowcatcher to rear coupler).

1947 Model - This model is the most desired of all 675 steam engines.
1948 & 1949 Model - Shown in first photo above. - Very similar to the 1947 model and just a step lower in collectability compared to the 1947 model.
1952 Model - The least sought after model. This has generated little interest in the collector market.
