There is bad contact in the track connections. You can sand the track connection sites. Another method is to run another power wire to the other end of the track where the train slows down. Even better is 3 or 4 evenly spaced power wires from the transformer to the track.

try reversing your wires from the transformer to the track.

From a top view there is a dot near a pin. That pin is #1 and numbering proceeds counterclockwise from 1 to 8. Pin 1 is the ground. You can see the article on Wikipedia for other info, if needed

The Lionel postwar 190watt transformer is an excellent power supply for trains. If one or more of the binding posts are loose ("U,A,B,C,D" Terminals") you will need to replace the binding post, use a T-159 replacement Binding Post. The original posts are soldered and crimped on.
The T-159 replacement binding post is bolted on. UNPLUG THE TRANSFORMER Carefully pull/pry up the handles and remove them remove the 4 Philips screws on the top, lift off the case top, the binding posts stay with the body of the KW.
Remove the loose bindings post one at a time as needed. Be sure to get any wire reattached. Reverse the procedure to reassemble.

I have had the same problem with my polar express, which i just bought recently. Having to send it to the USA from the UK would be very expensive so i decided to open it up myself. The tamper proof screws were a bit of a problem getting into it. I ground down an old screw driver into the triangle shape to undo them. I then replaced them with self taping srews the same size.
The Problem I found was simple, there is an internal (250V, 8Amp) fuse soldered onto the red wire on the secondary winding of the transformer. The red wire going from the transformer to the PCB, the fuse has black heatshrink over it.
There is no room inside the housing of the controller to fit a fuse holder. I fitted a box on the side of it with a panel mount fuse holder. drilled a hole through the housing, fitted longer red wires, so they could go through to the terminations on the back of the fuse holder.
At least now I can change it simply if it blows again.

hope this is of help to you.

I rewired my train this now works on my outdoor setup....I found that the circuit board inside the engine had a blown capacitor and the power transitor was fried. I by passed the engine board found that it only would run backwards....went into the tender and taped into the power from tack bypassing the rectifer... By the way the engine does not start up when one uses the remote...there is a 20 second delay before starting

On a postwar LIONEL ZW TRANSFORMER, Yes the red light will come on if a short is present with the throttle on. As soon as the throttle lever is in the off position the red light will go off. Shortly followed by the automatic circuit breaker clicking, as it cools and resets. The short on the track may still be present but with the lever in the off position the red light will stay off. There are several variations of the ZW 275 Watt transformer, early and late "type R" models. Both work the same but are wired slightly different the early ZW uses two 6 volt bulbs and the "Type R" uses two 18 volt bulbs. Internally if there is a resister connected to the base of the red light it will use the 6 volt bulbs.

indicates a dead short to ground in the smoke unit that is overloading the transformer
