Logos On Front Of Coaster Trains...

^That is a perfect design. Elaborate coaster art with the park name in a plainer font. Perfect combo.

However, in most cases, the park name on a coaster is for media purposes. Tatsu for example has "SIX FLAGS MAGIC MOUNTAIN" on car 2 of each train, due to the media day camera being afixed to the bottom of car 1.

 

I think that is pretty much it.

 

I'd also say they do it because when visitors take happy snaps of the rides, the park name will be right there...Good if for example you show it to other people, and they can then see the name of the place you visited....Its sort of like those photo ops parks have, such as those murals you stand behind, with your face showing through the hole. Without exception, they always have the park name.

 

They wouldn't do it to remind people what park they are in when they are there riding it on the day.
