Current yellow line Volvo B7TLs 32105-7 (LT02ZCU-X) are shortly to receive new lilac front ends following their replacement on the 28 and X29 routes by five of the former Leeds B9TLs. This is part of an ongoing plan to upgrade all the routes one after another. This also means the yellow saloons will look different too with at least one probably having a lilac front end.
Also reported on the Facebook First Eastern Counties blog is the future arrival of two more deckers at the end of the month
My thanks to my contact at First for the update and to Zak Nelson for the use of his photo.
