6000F-J - These are five different interface cables made up for the more popular computers (Macintosh, PC [9 pin and 25 pin], Apple II, and Commodore)

6001 - 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.

6017 - Booster which when coupled with a transformer provides additional power for HO and 1 Gauge Märklin layouts. Supplied with connecting cable which attaches to the 6021 Control Unit. An older unit with the number 6015 will also work with the 6021 if the dip switches on the rear of the 6021 are all down. This places the unit in the same control mode as the 6015. Other boosters which were made for the 2-rail Lenz cooperative digital program with Märklin are 6016 and 6018. This program is no longer supported by Märklin Digital and they will not work with the Märklin/Motorola data format.

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.

6036 - The Control 80f unit allows for additional stations to be located on a layout for addressing locomotives. It copies the controls found on the 6021 Control Unit. A total of ten control units (including the 6021 and 6051 Interface) can be connected together for layout control. An older unit with the number 6035 also allowed for all 80 locomotives to be addressed, but the 6035 did not have the extra four function control. These were necessary for operating the Panorama Car, Digital Dance Car, and the Digital Crane. Additional function decoders manufactured by Nacka in Sweden are currently available from dealers in North America. Future decoders from Märklin should also see additional function capability. Another type of locomotive controller using infrared technology was also once marketed by Märklin. The 6070 Digital Infrared Control 80f (receiver) and the Infrared Controller (handheld transmitter) 6071 were capable of allowing four person wireless walk-around control. These units are no longer manufactured but occasionally can be found in shops.

6038/39 - 25" and 72" extension cables for attaching various digital units to one another

6040 - Keyboard. This will control 16 solenoid accessories. LEDs show settings for turnouts and signals. Coding switches on the rear allow for setting the Keyboard address from one to sixteen. A total compliment of 16 Keyboards will control 256 accessories. Contains memory storage for the last valid turnout and signal setting after power is shut off. The Keyboard was supplemented earlier by the 6041 Switchboard which is no longer in production. It allowed operators of existing layouts with "track diagram control boards" to continue using those controls. The Switchboard connected directly to the buttons and switches mounted on the control board and was linked by cable to the Central Control Unit.

6043 - The Memory unit serves as a route controller. Several solenoid accessories can be switched with the press of a button. It stores in each of 24 routes the position commands for up to 20 turnouts or signals. A maximum of 4 Memory units can be used with the Control Unit. Position commands are entered with a Keyboard, Switchboard or Interface. Routes currently called up are indicated by LEDs. The routes and the last current status of the unit remain in memory storage after the power is turned off.

6051 - Computer Interface for integrating computer control into digital layouts. All 80 locomotives and 256 accessory addresses can be controlled through this unit. A connector for the s88 (6088) is located on the rear of the unit. This Interface is the same as the earlier 6050 with a few interior architecture changes. The Interface found on the 6023 Central Control-i had two communication modes and various baud rates. None of these are included in the 6051. It only communicates is "binary" mode. The other enhancements found on the 6023 were included there because of the educational nature of that unit. Those additions inhibit the full range of control which the Interface is capable of and so were not included in the 6051.

6073 - Turnout decoder for M track. These small single accessory decoders fit into the underside of M track turnouts. When wired to the track for ground and power feed, they have no other wires and simple connect to existing track on the layout. Very popular for temporary display layouts where a minimum of wiring is preferred.

6080 - Decoder for Märklin HO locomotives with alternating current motors. Can be controlled with the Control Unit (6021). Each has a single locomotive function such as directional lights, smoke or TELEX couplers. They can be coded for 80 different loco addresses. Dimensions 36 x 21 x 9 mm.

6081 - Decoder for HO locomotives with permanent magnet motors on both 2-rail and 3-rail tracks. Can be controlled with the Control Unit (6021). Each has a single locomotive function such as directional lights, smoke or TELEX couplers. They can be coded for 80 different loco addresses. Dimensions 36 x 21 x 9 mm. The Maxi decoder #65853 also controls DC motors and is specially designed for ironless core motors. The smallest decoder for permanent magnet motors is #66913 (14mm x 18mm). It was originally supplied in the Jägermeister railbus jointly manufactured by Märklin with the Bemo company. An older decoder #6082 was manufactured for the Märklin/Lenz cooperative work on 2-rail and is no longer needed for 2-rail layouts. The current 6081 will operate with all 2-rail and permanent magnet DC locos. Other decoders used in 3-rail locos with DC motors include 211410 for the 3611 and 3614 locos and 673470 for the longer tendered 3711.

6083 - Decoder for controlling turnouts, signals or uncoupler track. It can be activated by Keyboards, Switchboards, Memory or Interface units. Coding switches inside allow for setting decoder addresses. Each contains 4 outputs for double solenoid accessories. Similar units were once made for the old 2-rail program, the 6087 for HO and the 6086 for 1 Gauge, but they are no longer needed because the 6083 will work with both 2-rail and 3-rail and any scale layout from Z to 1 and G scale.

6084 - Decoder for turning on/off continuous current for lighting circuits or motors in accessories. Can be activated by Keyboard, Switchboard, Memory or the Interface. Coding switches inside allow for setting decoder addresses. Each contains 4 double relays. A similar unit were once made for the old 2-rail program, the 6074 for HO, but it is no longer necessary because the 6084 will work with both 2-rail and 3-rail and any scale layout from Z to 1 and G scale.

6088 - Feedback module for contact activators on digital layouts. It can be connected to the Memory or Interface units with the cable included with the unit. Connector sockets provided for additional s88 decoders. Each has 16 inputs for contacts. All 16 can be inputs when connecting to a computer Interface. If connected to a Memory unit, only 8 provide inputs for selecting routes, the other 8 release routes from the Memory. A 78" extension cable #6089 allows for more remote placement of the s88.

6090 - Digital Propulsion Set consists of a superior decoder and replacement field and magnet for converting alternating current motors to permanent magnet motors. These are for Märklin HO locomotives with drub style commutator motors. Adjustments on the decoder allow for maximum/minimum speed settings, acceleration and braking delay. Motor is monitored on ascending and descending grades to cause constant speeds. Can be coded for 80 different locomotive addresses. Dimensions 36 x 21 x 9 mm.

6095 - Decoder for single motor Märklin 1 Gauge locomotives. It can be controlled with the Control Unit (6021). Each decoder includes five functions and can be coded for 80 different locomotive addresses. Also includes adjustable maximum speed, acceleration and braking delay. built-in load-dependent speed control up hill and down hill. Dimensions 100 x 50 x 10 mm. Two motor locomotives require decoder #86095. Special decoders are also available for 1 Gauge Köf (#66152) and the T 3 locomotive (#66982). Two decoders no longer supplied by Märklin which were used in the Märklin /Lenz 2-rail projects were the 6085 single motor and 86085 double motor decoders.

6603 Delta Module. An electronic component for converting conventional Märklin HO locos to the DELTA multi-train system. Locomotives with the Märklin flat or drum-style commutator motor can be converted. Locos which are converted can be operated with conventional transformers when the addresses are set to zero, the DELTA Controller (6604) the DELTA station (6607) or the Digital Control Unit (6021). Headlights change over with the direction of travel. Headlights are on when the locomotive is in motion. Dimensions 36 x 21 x 4.
