One of a fairly limited number of locos that can operatre on Kato Compact Line 150 mm curves is their ED19 electric loco:
The prototypes were six locomotives built for the Japanese National Railways by Baldwin-Westinghouse in 1926.
They were built for the Japanese 3'6" gauge, but the proportions aren't far off for US standard gauge electric locos. With a 1-B+B-1 wheel arrangement, they seem to be fairly close to the New Haven EF-2.
The biggest difficulty I had with the loco was installing the number plates. Kato number plates and number boards are tricky and liable to shoot off into space in installation. On their US models, Kato provides extras in case this happens. On this model, though, you just get four boards per number, with no spares. You'd probably have to send to Japan for replacements and maybe try to explain things in Japanese.
What I've done with Kato number boards and number plates is use a small piece of Scotch Magic Tape, laid sticky side up. I press the number board or number plate onto the tape, number side down, into the sticky side of the tape.
Then I pick up the tape and use it to maneuver the number board or number plate into the recess in the body where it belongs. It's good to double check and make sure the numbers are right side up. It may take some jiggering around to get things exactly in line to go in, but the tape will keep things from flying off into space. When the board or plate is firmly installed, you can just gently pull the tape away.
With no spares, I was nevertheless able to get all four number plates installed in this loco.
