Setup of Electrical Gear

The electrical gear is in 3 boxes. The POD is a green plastic fishing box, and contains the DCC command station and booster, a “MagnaForce” 16VAC power supply for the accessory Buss, and distribution switches for the 3 main districts of the layout, The Outer Loop, the Inner Loop, and the Outer Yard (from the Barrel loader, past Brasor station, to the Roundhouse). The distribution switches allow you to select DCC or Off for each of the 3 districts. The Outer Loop can also be set to TMCC/AC.

The DCC throttles, radios (UR91 and UR92) and cables are in a black plastic box labeled DCC Gear. The TMCC equipment is in a plastic box labeled TMCC Gear.

 The POD sits under the Yard Expansion module, near the turntable. It normally sits on the transformer box. Open the top. Be sure the distribution switches are all set to Off (middle position).  The cables behind the switches all need to be connected. Don’t connect the cables in front of the switches (red and white barrel connectors, these are only for emergency use).

Three of the cables have two-color connectors. These connect to corresponding connectors hanging from the layout above the POD. They are: Green/White – Inner loop, Red/Black – Outer loop, Yellow/Orange – Yard. There is also a solid yellow connector that goes to the TMCC equipment, see next section. Finally, there is a telephone style cable which plugs into the back of the UP-3 which is in the layout fascia directly above the POD. There is a power cord which plugs into the back of the POD, and into the layout power strip. The MagnaForce unit plugs into the power strip, and its output cable (green barrel connector) connects to the corresponding cable hanging under the TV. This is the accessory buss.

To complete the DCC installation, install the UR91 behind Brasor station, and plug its white power supply into the closest 115V socket. Install the UR92 at Coughlan station. And plug in its black power supply.

There are 3 LocoNet cables in the DCC GEAR box. These have 6 pos Telco or RJ-45 style connectors on each end.  The first is labeled “Above command station to Coal Dump”. Plug one end into the back of the UP-3 above the POD, and the other end into the back of the UR92 at Coughlan Station area. The second goes from Coughlan Station and under new Lift Gate Bridge to one side of the inner  yard. The third goes from the other side of the inner yard to the UR91 behind Brasor. There are (2) DT402D,  (1) UT4D, and (1) DT400R throttles in the DCC GEAR box.  The UT4D should be used for the coal dump. Put fresh batteries in any throttles you plan to use. The *D throttles should be left unplugged once they are set up.

The TMCC gear is set up on the transformer shelf. The two boxes strapped together are the Base and the PowerMaster. There is a small black power supply labeled TMCC Base, that connects to the base and is plugged into the layout power strip. The cable from the PowerMaster with the solid yellow connector connects to the corresponding cable from the POD. The PowerHouse  plugs into the PowerMaster, then plugs into the power strip. The switches on the PowerMaster should be set to 180W and Run. Set the CMD/CONV switch based on what you want to run: CMD for TMCC (full voltage on track) or CONV for conventional AC (track voltage controlled by CAB-1 throttle). Leave the PowerHouse Off.

Operation:
Open the front of the POD, and turn on the (4) circuit breakers which power up the digitrax Chief and the NCE booster. There is a fan under the Chief which is turned on when you power up the chief, so be careful sticking your hand under the shelf to get out the programming track or documentation. When all 4 circuit breakers are on, the Chief and NCE booster should start up.

Close the front of the POD. Decide which tracks you want to run DCC on.  Check that the inner yard is not connected to the inner loop, and that the power switches on the inner yard are both set to Off. Typically the outer yard is left off, so that locos and cars can be displayed there. If you want to run DCC on the outer yard, be sure only DCC locos are sitting on any powered tracks.

We always run DCC on the inner loop, so be sure only DCC locos (and/or 1 DC loco) are on the inner loop. Typically we run the camera loco on the inner loop, and sometimes one other DCC or DC loco at the same time. Don’t let DC locos sit on a DCC powered track for more than a few minutes. When you are ready to power the inner loop, turn the corresponding distribution switch to DCC (up). Test the camera loco to be sure it is running ok, and that the camera is working. You may need to turn on track power using a DT402 or DT400R throttle.

Normally, the outer yard distribution switch is left off. If you want to run DCC on the outer yard, check that there are no DC, AC, or TMCC locos on the powered sections of the outer yard, then turn the Outer Yard distribution switch to DCC. TMCC/AC cannot be run in either yard.

The Outer loop can be set to either DCC or TMCC. If you are going to run DCC, be sure only DCC or DC locos are on the outer loop, then turn the distribution switch to DCC (Up).

If you want to run an (one at a time only) AC loco on the outer loop, be sure the distribution switch is off (middle position) then place the loco on the track. Be SURE it is an AC loco! Slide the CMD/CONV switch on the PowerMaster to CONV, this will allow the CAB-1 to control track voltage. Turn the PowerHouse on. Turn the Outer Loop distribution switch on the POD to TMCC/AC (down). The loco should not move. Pull the antenna out on the CAB-1, and press the Boost button. This wakes up the CAB-1. Then select the track by pushing the TRK button followed by the 1 button. You should now be able to operate the AC loco with the CAB-1, including Whistle and Bell if the loco has them. When you are ready to remove the AC loco, unless it is immediately being replaced with another AC loco, turn the Outer Loop distribution switch back to Off (middle position) and turn off the PowerHouse. This is required even if you are going to run a TMCC loco.

If you want to run a TMCC loco on the outer loop, be sure the Outer Loop distribution switch is off (middle position) then place the loco on the track. Be SURE it is a TMCC loco! Slide the CMD/CONV switch on the PowerMaster to CMD, this will cause the PowerMaster to supply full voltage to the track. Make sure the power supply for the TMCC Base is plugged in, and is connected to the Base. Turn the PowerHouse on. Turn the Outer Loop distribution switch on the POD to TMCC/AC (down). The loco should not move. Pull the antenna out on the CAB-1, and press the Boost button. This wakes up the CAB-1. Select the engine by pushing the ENG button followed by the locos ID number (normally 1). You should now be able to operate the TMCC loco with the CAB-1, including Whistle, Bell, and crew communication commands. When you are ready to remove the TMCC loco, unless it is immediately being replaced with another TMCC loco, turn the Outer Loop distribution switch back to Off (middle position) and turn off the PowerHouse. This is required even if you are going to run an AC loco.

Before moving any of the POD distribution switches from Off to either DCC or TMCC/AC, please check the track to be SURE the correct locos are on it. If something starts moving fast when you turned the switch, be prepared to quickly move it back to the Off (middle) position, then figure out what is wrong before turning the switch again.


 

Checklist:

  1. Place POD on box under Yard Expansion module. Check that circuit breakers are off (down) and distribution switches are off (middle).
  2. Connect 3 cables behind distribution switches (2 color connectors) to corresponding connectors hanging from layout. Leave the solid yellow (TMCC/AC) disconnected for now.
  3. Connect the RJ45 (telco) cable to the UP-3 directly above the POD.
  4. Connect the MagnaForce output cable (green barrel connector) to the corresponding cable hanging under the TV. This is the accessory buss.
  5. Plug the power cord into the POD (open the front and hold the shelf) and into the layout power strip. Plug the MagnaForce into the power strip.
  6. Install the UR91 behind Brasor station, and plug its white power supply into the closest 115V socket. Install the UR92 at Coughlan station. And plug in its black power supply.
  7. Connect the LocoNet cables from the UP-3 above the POD, around the layout ending with the UR91 behind Brasor. The cables are labeled.
  8. Place the TMCC gear on the transformer shelf. The yellow connector goes to the yellow connector in the POD. Connect the PowerHouse to the PowerMaster, and the Base Power Supply (WallWart) to the Base.
  9. Check the PowerMaster switches: 180W, Run, Conv.
  10. Plug the PowerHouse and the Base Power Supply into the layout Power Strip.
  11. Check all distribution switches are off (middle) then plug in Layout, and turn on Power Strip.
  12. Turn on MagnaForce. Accessories should light up (if installed).
  13. Turn on all 4 circuit breakers. Chief and NCE should fire up.
  14. Be sure only camera loco is on inner loop, move inner loop distribution switch to DCC (up).
  15. Put a battery in a DT402D throttle, turn on track power, select camera car, and test loop. Be sure TV picture works.
  16. Leave the Inner yard disconnected from the inner loop.
  17. Leave Outer Yard distribution switch off unless you really want to run something in the Yard.
  18. Leave PowerHouse Off unless you want to run TMCC/AC on the outer loop.
  19. Be sure only the correct locos are on any tracks that you are going to power.
  20. Think before changing the position of a distribution switch.
  21. To run TMCC on outer loop, be sure only TMCC or AC loco(s) are on outer loop. Set the PowerMaster switch to CMD for TMCC, or CONV for conventional AC. Then turn on the PowerHouse, and turn the outer loop distribution switch to TMCC/AC (down).
