Marklin released 88633 more than 10 years ago, it was their 4th NOHAB Diesel Locomotive. There have been another four released to date with little to no difference in appearance with paint and lettering for various railroads as the exception. This is a favorite locomotive type for me, I have all versions released by Marklin thus far. And one by FR which I would like to explore by way of contrasting the 2 companies interpretation of this locomotive. I chose DSB Class MY models with varying paint schemes to be close enough for this posting. Both companies are known for historical research based tooling and paint schemes, but when FR released their loco they claimed a higher level of accuracy concerning the NOHAB: time to consider the claim.

I will break down the post into the following categories: dimensions, weight, color, shell details, coupler system, wheel arrangement and mechanics.

Dimensions: buffer to buffer (FR 87mm / Marklin 86mm), body shell end to end (FR 81mm / Marklin 84mm), height from wheel flange (FR 19mm / Marklin 19mm) and width of body (FR 14mm / Marklin 15mm). Note: Marklin’s locomotive features buffers that are tiny and do not reflect what can be seen on prototypical locomotives (simple Google search will verify this conclusion). Further, Marklin’s DSB MY locomotive buffers appear to be comparable in size to the headlights. FR has modeled their buffers and body mounts more accurately to the prototype.

Weight: using a postal scale the FR weighs 1 1/2 ounces and the Marklin weighs 1 ounce. The weight difference is obvious in hand thus the FR model should be able to outperform the pulling capacity of the Marklin loco. Note: current Marklin Z NOHAB locomotive shells are cast with metal impregnated plastic which makes recent NOHAB’s a little heavier. Stayed tuned for a future post on this topic.

Color: as can be seen in the photos each locomotive exhibits different paint schemes which could be explained by the research each company performed. FR states the paint scheme they used is referred to as ‘economy without white striping.’ Examples can be found online with similar paint scheme as that used by Marklin.

Shell Details: this category maybe of particular interest to some collectors due to the number of differences. Marklin’s loco is clearly longer than FR, and Marklin 88633 is clearly wider. Roof is more rounded on the FR model. Roof equipment is slightly different on both models, but both appear accurate to their respective prototypes. Two styles of vents are used by each company, both are correct as can be seen from online photos of the prototypes. FR’s venting is very detailed almost 3 dimensional. One of the more consequential differences between the 2 models is body shape with the FR’s front and rear nose sloping at a dramatic angle versus the more squared off appearance on the Marklin, FR is closer in appearance to DSB ‘MY’ prototypes depicted in online photos, but the appearance of Marklin’s 88633 is very similar to other versions of the NOHAB painted and lettered for other railroads depicted in photos found online. Doors on the FR’s front and rear nose are cast versus suggested thru imprinting as on Marklin 88633 thus giving the Marklin a smoother finish. Add-ons for Marklin include lower step for cab access, on FR they include cab steps and railings. Marklin’s wider body shell gives its locomotive a boxier appearance, and its windows are small compared with the FR model. On the flipside, FR’s body shape is dramatic with narrower body and angled nose pitch plus those large windows.

Coupler System: connecting rolling stock to these locos could not be more different. Marklin uses their tried and true system which allows easy coupling and uncoupling with track #8587 whereas FR uses a simple wire which works well with the Marklin mini-club couplers, but it does not allow automatic uncoupling with Marklin uncoupling track section. If you display your locos the FR wire coupler virtually disappears.

Wheel Arrangement and Mechanics: one curious feature of the FR model is of course the snowplows which are standard equipment on Scandinavian trains, but missing on Marklin 88633. Marklin is missing the large pair of diesel tanks installed on the FR model’s chassis: not sure what is depicted between the Marklin’s wheel sets. The engineering and design of FR’s trucks conceal the wheels unlike Marklin’s design, I would further comment FR’s truck design is true to prototype, Marklin appears to be using a standard design they have used before which leaves top part 1st and 3rd pair of wheels exposed. Marklin wheel sets include metal gearing, FR fully nylon. Motive power on the Marklin 88633 is the very reliable 5 pole motor which was replaced in later models with motor featuring bell-shaped armature. FR has been using a similar motor for many years. And FR has been providing a choice: DC or DCC. FR’s digital (DCC) option includes extensive sound functions.

Conclusion: overall I would rate both locomotives as very good with the FR representing the prototype of a DSB MY locomotive more accurately plus FR offers a digital option. Marklin adopted a very interesting new casting feature: metal impregnated plastic thus current and future models have gained some weight which I will follow up on in a future post. Plus is there a difference between early versions of Marklin’s NOHAB locomotives and recent releases? I will follow up with a look at all released NOHAB’s to date.

Siding: FR Freudenreich has rebranded, the new company is named AB-Atelier Barkvieren. Packaging for the new company features red logo versus FR’s blue logo otherwise packaging is identical: clear acrylic boxes lined with dense white foam.
