From Erin Glover on the Disney Parks Blog:

If you’ve been to the Disneyland Resort in the past couple of days, you may have noticed a few new faces along the Disneyland Monorail line. Here to welcome their “Cars” friends to Cars Land at Disney California Adventure park, Mandy and Mona Monorails began making trips around the resort yesterday – and they will soon be joined by a third friend, Manny Monorail. You can tell each by their colors: Mandy Monorail is blue, Mona Monorail is orange and Manny Monorail will be red.

Come take a ride on the Disneyland Monorail and visit our three newest Disneyland Resort friends – Manny, Mandy and Mona Monorails!
The purist will hate it (in which i am). But its not horrible. I dont like alteration of an original but i dont run the company
I honestly think its brilliant, makes the kids appreciate the monorail as more than just a way to get to and from the park. love this! too cute
This is absolutely hideous and I hope they will remove it real soon. I feel its insult to the Mark VII Monorails as well as Walt Disney's original purpose as a possible transportation system.
Now if they can just add A/C to the monorail, we'll be all set.
The mouths look like shark mouths to me. Yhe do look good inperson.
I seem to remember monorail not going anywhere near Radiator Springs in DCA. So this enhances my Disneyland experience how? And boy that Car's theme looks so cool next to the Red Cars and 1930's DCA makeover. Unless Autopia suddenly went Car's theme, you folks did a disservice to monorail. I highly suggest this not be attempted on the Steam Enigines.
outside doesn't look bad but I can't get past the new cartoon spiels totally ruins the monorail experience! I always look forward to hearing the familer voice narrating, now its like being in an episode of Teletubbies and I can't wait to get off!
