You can straighten the tether and add a deck plate to make it almost disappear. I do that to all my older MTH engines. I would cost a bit more because you would have to get a full blown Cruise Commander and Railsounds but still a fraction of the cost of a Legacy engine and MTH Premier steam is every bit as rugged as this Dreyfuss and will smoke even better.
I don't want to hijack Alex's thread but you can see examples here.
