*sigh* I dont think you should EVER remove a carousel, if its a classic one.
None of the carousels at the Towers have ever been classic carousels. They've pretty much one and all been off the shelf models. The only carousel the park has ever had which has been truely unique is the Doodle Doo Derby.
Of the Cred Street Carousel and Gallopers, whilst the Cred Street was certainly the more striking of the two, I believe the Gallopers are technically the better crafted ride, using better quality materials and design (for example using real horse hair for the tails).
That said, I would agree with the above, and say the reason the Gallopers was the ride which was saved comes down to the fact its easier to maintain (and also has a smaller footprint)
Edwardo..... move me!
