Sounds wonderful - who knew a bus could have rhythm?!
Not sure which particular engine models were involved, but back before BL started putting adequately powerful turbodiesels into Land Rovers, people used to drop an assortment of light-medium commercial engines into them to replace the woefully underpower NA 4-pots they’d been equipped with since the Late Palaeolithic. V6 Cumminseseses were among them.
Considered it myself, but questions concerning the radically altered weight distribution, brake-sufficiency, and gearbox-liquidising amounts of torque went unanswered and the ‘project’ was swerved! 
The Shetland bus, or one of them. The Andholmen, a Norwegian fishing boat that ferried people and cargo during WW2, over for the VE day anniversary. A distinctive sound from the single cylinder semi-diesel.

This seems to be a common fitment. I only know it from Dennis Dart models Ive driven over the years!
The Cummins V6- according to various books and magazines in my collection- wasn’t at all reliable and it used a lot of fuel compared to the Gardner lumps of that time.
You dodged a bullet!

My longest drive in a bus was behind the wheel of this machine.
Nippy and very difficult to keep to 50* because she wanted to keep accelerating!
The Leyland TL11 is my favourite sounding engine. Effortless torque- not like the rev-happy four and six bangers I was accustomed to!
*On Motorways in order to save the hub reduction rear axle seals from blowing.

A surprisingly successful Power Unit, this.
Launched in 1948 as the O.600, the unit was produced under licence by DAF, Mielec - until the mid to late 'nineties and of course Ashok Leyland:
You’ve all heard this familiar sound at some point.

I must say that the alleged speed of this bus is somewhat exaggerated. It is an Alexander Dennis Enviro 400 with a 6.7L 245bhp Cummins ISB Engine* and a ZF Ecolife 6 Speed Auto Gearbag*.
It’s top speed is likely geared to 45 mph. They may get there. Eventually. City Buses do not need to be fast!
It is highly unlikely that the Service Brakes would just fail. It isn’t like a car which has a split circuit hydraulic braking system!
It has Air Brakes. Depending on generation, these will be fitted with an EBS based Braking System:
The failsafe Spring Brakes prevent the vehicle from moving if there’s insufficient air pressure:
Brake Actuators Brake Actuators
The driver did well to keep it upright and lose momentum in that river.
*These two are controlled electronically; they ‘communicate’ with the EBS System too. Also, accelerator pedal cables haven’t been a thing for at least 20 years!
