The answer is no. The old school transformer used by Lionel under the black cover, was a unique creation and has been usurped by the complexity of taking the heart of the thing, now a simple almost off the shelf low voltage transformer in a couple sizes depending on needed wattage, the larger ones a 'brick' as people call them, and taking that AC though Triacs or other components to make variable AC track control volts. The original Lionel transformer with open windings for the rheostat, has become very expensive to make. I'm sure there are a ton of OSHA rules that apply also, compensating for the idiot factor of many folks today who could break and anvil if given the chance. The CW 80 is small enough for it all to be in one case, the CG180 has an outboard AC supply feeding the electronics in the control half of the unit. There are many original Lionel units for sale just about everywhere, and as long as structurally intact, and with a good transformer, repair is usually just a new line cord and maybe the whistle control rectifier, and some clean up. Attached are 2 photos covering a schematic of the CW 80 I found, note that unlike a normal Lionel transformer where A B were variable, they are fixed and the U terminal is what is changing. Guessing the CG180 is basically the same, but with bigger Triacs.
