Great video. ☺️

[@CardenasBlack]

The memories just come flooding back 😢😢😢😍

[@BusesInDublin]

Wow that's amazing 😍 reminds me of 2975 in the Translink Metro fleet in Belfast!

[@dt9960]

Yep amazing is the word!

[@KickdownLondon]

Lovely!

[@NC-002]

Sounds fantastic! We want more like this!!

[@EnviroExplorer]

This thing was a beast when I had it on X3 (do have a video up) but the ZF wasn’t this loud ! Must’ve had a gearbox swap which has been happening with a fair few of the B7s and Tridents lately

[@dt9960]

You're lucky to get it on an X route! Trying to get 4487 on one, that one has a crazy ZF! Do gearboxes get swapped from buses with different chassis? This ZF is way too loud for a B7TL imo!

[@EnviroExplorer]

@@dt9960 I’ve just seen your comment on my video, may not be a swap on second thought. But answering your question, don’t think so. Normally just swapping a Voith out of a dead Trident into an otherwise better condition one and vice versa. Although not related to the B7s, most of the Cummins ISB engines fitted to Y plate Tridents were transplanted to E400s too

[@dt9960]

@@EnviroExplorer Alright, yeah that makes sense. So most of the E400s have the ISB engine? That's wicked!

[@jackb9016]

4480 is another loud one for you guys to go hunt! 4481 and 4489 no longer whine anymore though :(
