And even that is not true! There is only one exhaust on the GP40.
Here's a MTH review of the GP40 in question... You can clearly see when they fly over the top of the locomotive there is only one exhaust.
Wow. That's kinda bad that happens as often as it does.
When I preordered my Legacy Camelback from the Lionel vol 1 2021 catalog, Lionels website dicreption stated that it had a swinging bell and blow down steam. Turned out it was a copy and paste error and was corrected.
You folks that are seasoned train hobbiests know when there is an error like these so it is no big deal but it hurts the folks that don't know the details of the real life train.
We rely on these descriptions. Of course that's why it's nice to have help through this forum.
