Train Trek™ Automation Station
Basic Requirements

Back to Automation Station Page

Train Trek™ Automation Station was especially designed for the Märklin Digital/Delta system. The next is a minimal setup that is needed for Train Trek™ Automation Station operation.

Märklin Digital Components Required - Minimum Setup

1. Central Control : Catalog #6021 - This is the Central unit for Märklin HO and 1 Gauge digital layouts. It has a built-in locomotive controller. It supplies the layout with power and control commands. The built-in locomotive controller has the same features as the Control 80f (6036) Terminal clips on the rear of the unit are for transformer connections and track connections. The multi-pin connector is for adding Boosters. Maximum output current 2.5 amps. Earlier control units which are no longer produced include the 6020 Central Unit (functions the same as the 6021 when all dip switches are down), the 6022 Central Control which addressed four locos and four turnouts. This was included in most Digital Starter Sets in Europe. A similar unit, 6023 was called the Central Control-i because of the additional Digital Interface included in the controller. It was primarily designed for the education market around the world, but was also included in the starter sets in North America. The units which were part of the Lenz/Märklin 2-rail program included the 6027 Central Control=, the 6029 which was a combination of the 6027 and a Control 80f unit, the 6030 for 1 Gauge operation and the 6032 Programmer which was necessary for programming the early 2-rail decoders. Märklin now has the capability with the Motorola "pulse stream" format to address any loco (2-rail, 3-rail, AC or DC). Because of this advanced technology, the older 2-rail format is no longer necessary or supported by Märklin. 

2. Computer Interface - Catalog #6051 - The Märklin Digital Interface is the link between a computer and the Märklin system. Using serial interface connections, the computer can send commands to the interface, thereby simulating all the functions of the Control 80F and Keyboard units. Therefore, any computer with a serial interface can be used to control all locomotives, as well as solenoid-operated accessories (switches, signals, etc.). Two types of Interfaces have been available: 1) the 6051 Interface attaches to any of the digital systems, and 2) the 6023 Interface which is built into the Central Control-i Unit which came with early Digital Starter Sets and was also sold separately.

The computer can (via the Interface) receive and evaluate data from switching contacts such as contact tracks, circuit tracks, and reed switches as shown below. This is accomplished by incorporating s88 Decoders into the layout. In all, up to 80 engines, 256 switches, and a maximum of 496 track detectors can be controlled or monitored with the Interface. The Interface plugs into the right side of the Control Unit or a Control 80f unit. If Control 80f units are also attached, care must be taken to insure that engine addresses do not conflict between the two units. The computer plugs into the right side of the Interface unit with the 6 prong plug provided with the Interface. The computer user needs to construct a cable that will be compatible with the interface signal or purchase a ready made cable through their dealer. Serial connections use five wires to transmit data: 1) the "TD" line which carries data from the Interface to the computer, 2) the "RD" line which carries data from the computer to the Interface, 3) the "CTS" line that acts as a controller from the Interface telling the computer when it is ready to receive more data, 4) the "RTS" line that acts as a controller from the computer telling the Interface that it is ready for more data, and 5) the "GND" for the ground line. The other end of the cable needs to be compatible to the computer being used.

6051 Interface

There are 4 encoding switches on the rear of the 6051 Interface. These must be set according to the transmission requirements of the particular computer. This should always be done when power to the Interface is OFF. The first three switches can be set for positive or negative logic (up is negative logic). The fourth switch sets the transmission level for TTL or RS232 (up is TTL, down is RS232). Switch #1 is for the RD signal, #2 is for TD, and #3 is CTS. The newer 6023 Interface does not need switches. 

Train Trek™ Automation Station is designed for MS Windows 98/ME/2000/NT/XP. 

All IBM computers will follow this logic on the Interface DIP switch settings:

Switch 1 - Up Position

Switch 2 - Up Position

Switch 3 - Down Position

Switch 4 - Down Position


6023 Interface

The Central Control-i Unit (Märklin No. 6023) is no longer offered, but it offered some expanded interface commands and had the drawback of only allowing the connection of three s88 decoders. The communication modes included both ASCII mode and terminal mode (Binary Mode). When first initializing the interface in the Central Control-i Unit, the default mode will be the ASCII mode. This can be changed by pressing the "stop," "go" and function "off" keys simultaneously at the control unit and then letting go of the "stop" and "go" buttons first, then the function "off" button last. This resets the interface to the binary mode as in the 6051 interface.

With the interface in the Central Control-i Unit, control of trains can be transferred between the computer and the control unit. If an engine number is called up on the Central Control-i Unit, that same number can be called by the computer at which time, the LED on the control panel will go off and the computer will take control of the train. Likewise, control of an engine can be taken from the computer by the Central Control-i Unit.

3. Transformer : Catalog #6001/6002 - Transformer for supplying power to the 6021 Control Unit, 6015 booster, or 6607 DELTA Station. Suitable for supplying power to Märklin accessories on conventional layouts also. 42 VA output, 16 volt alternating current. Not recommended for outdoor operation in moist situations.


* You may also work with the Central Unit, Control 80 or Control 80f. These are older models but are compatible with Train Trek™ Intelligence.
