Ok, so I was thinking, nearly every set that you purchase now days includes an observation car. For example, the Williams 4-car sets and most Lionel 4-car sets include them.
In the case of the Williams Semi-Scale Heavyweight 4-car sets, has anyone ever swapped out the observation end of the cars with the standard end from a middle car to make another intermedicate car? Are the car ends available from Williams? Are they already painted?
I have included a picture of my idea...
Thanks for your help!
Sincerely,
Mario
