Troubleshooting Tips
      (See TMCC below)
      TMCC has some special circumstances which need to be
      recognized and considered. These include wire constructed
      tunnels, overhead tracks, metal bridges, powered metal
      buildings and similar circumstances. These situations
      sometimes present a disturbance in the TMCC signal.
      These TMCC and Legacy Wiring Tips are not intended as
      the required method by which TMCC or Legacy must be wired.
      Rather, they are suggestions for things to look at to maximize
      the TMCC or Legacy experience if TMCC or Legacy is not
      performing perfectly on a particular layout. Typically, TMCC
      and Legacy both function just fine right out of the box and
      in the vast majority of wiring topologies, there is no problem.

          1. Make sure you have a good ground on the Command Base.
              The AC adapter that came with the Command Base MUST be
              plugged into a well grounded 3 prong plug for TMCC to work
              properly. If that is not available, on the 3 to 2 adapter there
              is usually a little tab off the ground prong. Run a piece of wire
              from it to a water pipe or other known good earth ground.
          2. Wire mesh tunnels.
              Chicken wire used in conjunction with tunnels can cause
              a loss of TMCC signal. This can be avoided by adding an
              extra wire along the track, hidden inside the tunnel or
              by ballast, to help keep the signal strength up.
          3. Metal effect of buildings.
              To overcome the metal effect on TMCC just ground the
              metal parts to earth ground. You can get earth ground
              from the center screw a receptacle plate and or your
              water pipe. A metal floor on the bridge will effect TMCC.
          4. Increase signal strength in diesels.
              If you are having trouble with a particular engine, an easy
              way to increase signal strength is to install self adhesive
              aluminum tape inside the cab and all you have to do is lay
              the original antenna on top of it held on by simple scotch
              tape, as long as it makes contact it will greatly increase
              the resistance to dead spots.
          4a. A user's experience with a poor signal on a specific locomotive.
              I added a 2"x3" double thick piece of foil to each diesel
              by taping it to the inside top of the plastic housing.
              A little piece of wire and solder guaranteed a good
              electrical connection between the foil and existing
              antenna. Problem solved on every diesel! I can now creep
              my Odyssey RS11 through the metal tressel bridge blowing
              my horn all the way.

Whistle horn
      1. Provides a real-time adjustable horn control that is a variable
          lever operated by user, allowing engineer-controlled
          whistle horn blows just like a real train, with precise
          control for signaling in different situations

      1. Continuous warning sound on and off

      1. A real-time multi-position sprung lever control for boosting
          speed, holding that speed, adjusting it, or returning to
          original speed by letting go of the sprung lever, with
          realistic laboring chuffs on steamers and labored rpm
          changes on diesels (prototypical amount of rpm levels)
      1. A button that keeps increasing speed as long as it is held down.
          When it is released, engine returns to original speed

Independent Engine Brake
      1. Provides a real-time adjustable multi-position sprung lever for
          braking speed, holding the new speed, adjusting it and
          returning to original speed by letting go of the sprung
      2. Brake sounds change in intensity according to user position of
          brake lever
      3. Velocity throttle braking at a realistic rate based on momentum
          settings and engine speed without using a lever or
      1. A button that keeps braking speed as long as it is held down.

TMCC2 has a control mode "Velocity Throttle Sequenced Control", where the train speed, whistle, bell, crew-talk, brakes direction, start-up, shutdown and blow-down effects are controlled prototypically by using only the throttle. Another "extra" worth mentioning here is a "Feedback Effect" that shakes the remote when your train is laboring hard or braking with a lot of force. TMCC2 Legacy's "back pages" include Engine Specific Sequence Tuning, Route throw speeds, Engine Type information for custom control panels, battery monitoring, compatibility and readouts.
