What is the difference between Class 800 and 802?

So, what's the deal with Class 800 and 802 trains, huh? I was wondering that myself the other day, actually, because I was planning a trip down to Cornwall – you know, stunning scenery, but also, famously, hills! Lots and lots of hills.

The main difference, I learned, is basically power and range. The 802s are like, the beefier cousins. They've got a more powerful engine – think of it like the difference between a little moped and a proper motorbike, you know? This is super important for places like Devon and Cornwall, because those hills are killers. I remember once being stuck on a train going up a hill, it felt like forever! Seriously, I thought we'd be there all day.

The 802s also have a much longer range running on just diesel. This means they can go further without needing electric power, which is handy, especially on those less electrified lines. It's all about being able to reach those more remote areas, I guess. Makes sense, right?

And then there's the brake resistor thing – something about it being bigger on the 802s. Honestly, I'm not entirely sure what that means, technical stuff is not my strong suit! But apparently, it's important for braking, especially on those steep inclines – helps prevent overheating I think. I read somewhere that it’s a significant improvement over the 800's system, something about improved regenerative braking efficiency... or something like that.

Anyway, bottom line? If you're heading to Cornwall and you see a Class 802, you’re probably in good hands for a smooth (hopefully!) journey, even up those crazy hills.
