"Aren't they using the dual power ones ?"The hybrids? No, not on the E2. They use Volvo-engined buses, the B9TL version. TfL had many complaints about the previous Volvo B7TL, and at one point stopped ordering Volvo-engined buses until about 400 B7TLs had been modified to reduce the noise from the cooling fans.I don't know whether the B9TL suffers from a similar problem. If anyone thinks the noise is excessive, they should complain to TfL. Experience with the B7TL shows that complaints can result in action being taken.
