Märklin HO
Model BR 245 (29479)
Information about the Prototype
The German Railroad (DB) began searching for a replacement for the heavily used class 218 diesel locomotives almost four decades ago. The new locomotives needed to be capable of hauling medium-heavy regional passenger and freight trains without issues. DB ultimately found success with Bombardier, which offered the single-motor diesel locomotive class 246 from the Traxx family. This diesel-electric unit performed excellently for several years, pulling Metronom bi-level trains between Hamburg and Cuxhaven.
However, new exhaust regulations made further production of the class 246 difficult. Bombardier opted for a different approach: instead of a single large diesel motor requiring modification for exhaust regulations, the 19-meter (62 feet 4 inches) long, 83-ton locomotives were equipped with four individual, smaller diesel motors that met the new EU exhaust regulations Stage III B.
Convinced by this variant, DB signed a framework agreement with Bombardier for the delivery of 200 new class 245 locomotives. After successful test runs with prototype road number 245 001, DB-Regio immediately ordered 20 units for the regional areas of Frankfurt/Main, Mühldorf, and Kempten. These locomotives can reach 160 km/h (100 mph) and are powered by four six-cylinder Caterpillar CAT C18 diesel motors, providing a total output of 2,252 kilowatts (3,062 horsepower). Their acceleration is notable. On June 10, 2014, DB's long-distance passenger service group ordered seven additional 245 units to replace the class 218 Sylt shuttles, with a single 245 replacing two 218 units.
Safety Notes
- This locomotive must only be used with a compatible operating system (Märklin AC, Märklin Delta, Märklin Digital, DCC, or Märklin Systems).
- Only use switched-mode power supply units and transformers that match your local power system voltage.
- The locomotive must never be powered from more than one transformer simultaneously.
- Always adhere to the safety notes in the operating instructions for your specific operating system.
- For conventional operation, the feeder track must be equipped with interference suppression. Use the 74046 interference suppression set for this purpose. This set is not suitable for digital operation.
- Do not expose the model to direct sunlight, extreme temperature fluctuations, or high humidity.
- WARNING! Functional sharp edges and points are present.
- The LEDs in this item comply with Laser Class 1 according to Standard EN 60825-1.
Important Notes
- The operating instructions and packaging are integral parts of the product and must be kept and transferred along with the product when passed on to others.
- For repairs or spare parts, contact your authorized Märklin dealer.
- Warranty and guarantee are provided according to the enclosed warranty card.
- Disposal information is available at www.maerklin.com/en/imprint.html.
Functions
- Automatic recognition of the mode of operation.
- Mfx technology for Mobile Station / Central Station.
- Factory name: DB AG 245 006
- Factory address: MM 24 / DCC 03
- Locomotive parameters (address, acceleration/braking delay (ABV), maximum speed) can be set via Control Unit, Mobile Station, or Central Station.
- Direction-dependent headlights.
- In analog operation, only the driving and headlight changeover functions are available.
- Various controllable functions.
Note: The digital protocol with the most possibilities is the highest-order digital protocol. The sequence of digital protocols in descending order of priority is: Priority 1: mfx, Priority 2: DCC, Priority 3: MM. If two or more digital protocols are recognized on the track, the decoder automatically selects the highest-value digital protocol. For example, if mfx & MM are recognized, the mfx digital protocol is selected by the decoder. Individual protocols can be deactivated using Parameter CV 50.

CV 50 Alternative Protocols
This table defines how different digital protocols (Analog AC, Analog DC, DCC, MM, mfx) can be activated or deactivated using CV 50 values (0-15). A checkmark (✓) indicates an active protocol for a given value. The currently used protocol cannot be deactivated.
Maintenance and Service
Coupling and Uncoupling
This diagram illustrates the process of coupling and uncoupling the locomotive. It shows a tool (resembling a bottle opener) used to manipulate the coupling mechanism. An arrow indicates the direction of movement for engaging or disengaging the coupling.
Replacing Traction Tires
This diagram shows the steps for replacing the traction tires on the locomotive's wheels. It depicts the locomotive body separated from the chassis, a bogie, and a close-up of a wheel with a traction tire being removed or installed. The process involves detaching the bogie and carefully manipulating the tire onto the wheel rim.
Lubrication
This diagram indicates the lubrication points on the locomotive chassis. It shows an oil can symbol with '40h' (suggesting lubrication every 40 operating hours). Specific lubrication points are marked on the underside of the chassis, where Märklin 7149 oil and TRIX 66626 grease should be applied to ensure smooth operation of the gears and axles.
Spare Parts
Exploded View Diagram
This diagram provides an exploded view of the locomotive, showing its various components disassembled and numbered. This visual aid helps in identifying individual parts for replacement or repair. A note indicates that the details in the representation may differ slightly from the actual model.

General Note to Avoid Electromagnetic Interference
To ensure proper operation, a permanent, flawless wheel-rail contact of the vehicles is required. Do not make any changes to current-conducting parts.
FCC Compliance and Company Information
Due to differing legal requirements regarding electromagnetic compatibility, this item may be used in the USA only after separate certification for FCC compliance and an adjustment if necessary. Use in the USA without this certification is not permitted and absolves Märklin of any liability. If such certification is desired, Märklin should be contacted, also due to additional costs incurred.
