What you won’t read.  Quick maths to see how much capacity the 24 will lose when shiny new Borismasters take over in June:

Current:

  • PVR 27 (buses on the road at peak time)
  • Current mix of buses:
    • 5: H39/21D Volvo B5L / Wrightbus Gemini 2 hybrid double deckers (VWH’s)
    • 24: H39/23D Volvo B9TL / Wrightbus Gemini 2 double deckers
  • Assuming all 5 lower capacity hybrids are in use along with 22 diesels that’s
    • 39*27  = 1053 top deck seats
    • 21*5 + 23*22 = 611 lower deck seats
    • All of these can carry up to 87 passengers* as they come in 100kg under the 12,000kg mark, so that’s 27*5 for the hybrids and 25*22 for the diesels = 685 standees
  • Future 27 NB4Ls:
    • 40*27 = 1080 top deck seats
    • 22*27 = 594 lower deck seats
    • 18*27 = 486 standees

Summing up we go from:

  • Top deck: 1053 to 1080, increase of 2.5%
  • Lower deck seats: 611 to 594, decrease of 2.8%
  • Standees: 685 to 486, decrease of 29.1%
  • Lower deck total: 1296 to 1080, decrease of 16.7%
  • Total capacity: 2349 to 2160, decrease of 8.0%

I’ve no idea how crowded the route is at present, but losing 16%+ of your lower deck capacity overnight would hurt most inner London routes where people don’t always check upstairs.

* Wrightbus actually claim 91 as a maximum with 29 standees on the two door B9TL, but I’ve gone with the TfL specification of 87.
