Digitrax Releases New DT602/DCS52/UT6/UR93 Firmware Update

Digitrax has released a new DT602 firmware upgrade dated 31Mar2021. There is also an update for the DCS52 dated 26Mar2021. These upgrades include fixes for writing to extended CVs (above 255, the author helped beta test this on Soundtraxx decoders and it works!). There are also updates concerning the fast clock and timing issues with UR92’s with extended slots on/off. There is still an issue with the fast clock where entering a value of 11:00PM will result in a value of 5:00AM. As far as the author knows this will be deferred to a later firmware update (he was not able to test this due to lack of time).

Lastly there is a change to the switch commands. When a closed switch command is sent from a throttle a closed and open LocoNet message is sent, with the open command ignored.

So now when you push a closed command and hold it, a LocoNet message will close a turnout and then respond to the open command once the closed button is released. The author also did not have time to test this.

Glad they were able to fix the extended CV writing! This was an important one.

The updates are available on the Digitrax website here.

There was also an update to the UR93 which has not been released yet. Unfortunately, the author was not able to partake in testing this as he utilizes a UR92.

Atlas Buys Select M.T.H. Premier O Scale Tooling

M.T.H. Electric Trains has announced that it has sold a selection of its Premier O Scale molds to Atlas as part of its continued divestiture of tooling assets. For more information concerning this sale along with a link to the complete listing of the tools and molds purchased go here.

A discussion from Atlas concerning this purchase is located here.

A Statement From ScaleTrains on the MTH Acquisition

In a prior post the author wrote about ScaleTrains acquiring the M.T.H. S and HO scale tooling. Shane Wilson, president of ScaleTrains.com, issued the following statement:

“We are designing and tooling new motor mounts so the (MTH) locomotives can use our motor. We’re also designing a new main board so we can utilize ESU-Loksound DCC & sound. We have no plans to extensively rework the external details of current MTH HO and S models. We’ve received feedback about potential dimensional and detail issues with specific products and will take the information under advisement. If the issue can be fixed with a limited amount of time and money, we may make the investment. If the issue cannot be resolved easily, we may continue with the model as is or retire it.

Our team was a part of the GP7/9 and ES44 tooling acquisitions at our previous (Athearn) employer and we know how much time and money it cost to bring these models into the Genesis line. Starting from scratch would have been less time consuming and less expensive. 

If there is a current model in the MTH HO line-up that does not meet our Rivet Counter or Museum Quality standard and we believe there is a market in the Rivet Counter or Museum Quality lines, we’ll start the project from square one.

MTH has designed and engineered several steam era locomotives, freight cars, and passenger cars that are yet to be tooled. Over the next several years, we’ll bring many of these projects to market. Since they are designed and not tooled, we will ensure they meet Rivet Counter or Museum Quality specifications. Thank you. SW.”

40' Refrigerator Car Prototype History

The refrigerator car, first used in the 1880’s, was a major factor in the development of large farming areas in remote regions of the United States. The citrus and vegetable industries of the Southwest were largely developed after refrigerated cars were invented that could keep products fresh and edible while in transport. During the harvest seasons, thousands of loaded refrigerator cars are still sent to metropolitan areas from the South and Southwest.

Refrigerator cars also brought an end to the famous cattle drives of the "Old West”. Instead of driving cattle long distances to a rail head or packing plant, the expanded rail systems and development of refrigerator cars permitted slaughter houses and packing plants to be located near the large ranches of the South and West. This allowed the shipment of fresh meat over great distances without fear of spoilage.

Early “reefers” were of all wood construction and about 36’ long. Ice bunkers were built into each end of the car and filled through hatches on the car roof. These reefers could only travel about 250 to 400 miles before they would need re-icing. Salt was sometimes placed in the bunkers to make the ice melt faster and lower the temperature of the load. Railroads built huge icing platforms and ice storage houses at major terminals and other strategic locations to quickly service the cars.

Ice "reefers," with their telltale roof hatches, enjoyed a long life because of continual improvements in their design. Originally the cars relied on gravity airflow (cold air stayed near the bottom of the car) to keep loads cool. Loads were hung from racks or stacked on pallets and the cool air circulated around the load. Later cars used mechanical or electric fans to force cold air around the load. ln 1958, the first mechanical reefers (utilizing diesel powered refrigeration units) went into service and by 1971, the “ice age” had  come to a chilling end.

Traveling across your pike in a “block” or spotted on a siding at an icing platform, packing plant, warehouse, or brewery, these cars will add a touch of realistic color to your model railroad.

1910-1925 With Wood Ends

The all wood reefer represents the earliest cars, built with vertical brake staff and arch bar trucks. Many of these cars were painted with the advertising and slogans of private companies. These “billboard” lettering schemes make this series of cars very colorful.

1925-1950 With Dreadnaught Ends

As with box car development, steel components were incorporated into construction as technology improved. Stamped steel ends were added to the refrigerator cars to strengthen the body. “Double sheathing” remained a prominent part of the construction to insure maximum insulating properties. Equipped with steel roofs and Bettendorf trucks, these “reefers” could still be seen in trains during the 50’s.

1940-1960 All-Steel Refrigerator

By the 1940’s, new reefers were being built entirely of steel. insulating techniques improved to the point where economical refrigeration could be accomplished using steel side sheets in place of wood sheathing. Cars with steel roofs and sides were more durable and required fewer repairs than wood sheathed cars.

1960-1970 Plug Door Refrigerator

The plug door was introduced in the 1960’s as an option that provided a larger door to ease loading and unloading of certain commodities. These tight-fitting doors were better insulated and could keep the car at a more even temperature.

Variations of 40‘ refrigerator cars are available in limited numbers from Walthers including the double sheathed all-wood reefers, the double sheathed wood reefer with Dreadnaught ends, the all-steel reefer and the Plug Door cars. Walthers models are in the part number range 910-421XX where the X’s represent various numbers. They also carry a large line of refrigerator cars from various manufacturers. You best bet is to go to their website and search for 40’ refrigerator.

Thanks to Walthers for much of this information. The images are the author’s with the exception of the Plug Door reefer.
