Does the 1.5 mile run work as the displacement between the two garages or as the shortest driveable route?

Ok so quick question, what's the mechanical difference between new DD and SD ADL MMCs? Why is double deck so much smoother on braking and more responsive on accelerating compared to single deck which hiccups to accelerate and then braking is jerky? My theory at first was they're basically the same, it's just that DD's are heavier so they are being pushed down by weight, therefore the engine does what it's supposed to do and doesn't make bus hiccup on acceleration unlike SD which is lighter, so the engine is basically overpowered? Need answers lol.

Need answers lol. Most¹ of those double deck variants are hybrids and don't have conventional gear changing, which greatly accounts for the smoother acceleration and deceleration. Another aspect is that the hybrid deckers are driven by the electric motor. ¹ - barring the micro-hybrid on routes like the 136

When I just done type training on new MMC's awhile ago I thought there is something wrong with them...even old training vehicles were much nicer...I guess it's a cost thing over comfort.

I know ST812 is 0.2m shorter than the LTs, but why was it [ST812] built?

Does anyone know how the heathrow free travel zone work dor buses? What’s stopping me from boarding at say heathrow central, telling the driver I will get off at the next stop, and then stay on for te entire trip? Do people not tap in? If they tap in, how does the card reader know which one to charge and which one not to?

People getting on buses can just walk past the driver, and needn't tap the reader if they're travelling in the freeflow zone. Of course, inevitably, you get lots of fare dodgers who get on at Heathrow for free, but then use the bus to go beyond the freeflow zone.

Ok I have tapped in every single time at heathrow central (X26, 285, A10 and 140) so have contributed to tfl’s Coffers!

Can anyone give a view on how well new route 301 is doing in terms of usage / reliabilty?
Not seen much comment on what is a rare thing - a brand new route.

The route is certainly being used very well. There's multiple reports and a few photos of it carrying very healthy loads. Out of Bexleyheath it seems to be a popular alternative to the 401. However there was a lot of publicity from bus enthusiasts who took it upon themselves to put up posters which no doubt would have helped.

It was quiet on my one trip being on a Saturday afternoon at lunchtime so can't glean too much from that but echo Eastlondoner62 comments as I've heard multiple reports that it's doing well

It’s particularly useful at the end of the school day where the 401 is not now getting nearly such a pummelling at Bexleyheath. I use it most Tuesday nights to the stop at the top of New Road and it’s very useful. Only thing really is an increasing and worrying noise of complaint coming from residents and car users on New Road. Add the 469 to this and there really could be fireworks, and not of the pleasant kind.
