Gsgood,
It appears as though you are using "SOLID" Wire from your Xformer. If you are, switch to "Multi Stranded Copper Wire" to feed your Track. I would recommend a minimum size of 16 Gauge! Also if you intend on running any of your Old Conventional Engines with LEGACY, you will need an interface between your ZW and the Track, such as a LIONEL POWERMASTER, a TPC 300 or TPC 400.
