all you need to do is make the proper decals and your good to go with MTH Subway. I bought my first subway set when MTH last produced them. A friend of mine had the correct logos, put them on for me - problem solved.
The item numbers are 20-21142-1 - O Scale Premier R40 4-Car Subway Set with Proto-Sound 3.0
The item numbers are 20-21142-3 - O Scale Premier R40 2-Car Subway Set Add-On (Non-Powered)
The proper logos were installed and then they were put in the box. Unfortunately, I never took pictures or even tested them. The on complaint I had was with the dealer for using crappy packaging when it was shipped which cause the purple box to be damaged.
Other than the minor change I made they look great.
