The 458 has scored too highly, but the 717 is too low, that staircase is brilliantly integrated.

Hear me out: the class 700 is a really good train, they will last forever, very good build quality, it’s got great passenger screens and they have huge capacity. The only things wrong with them is that they have bad seats.

Also 376 and 466 are great for their job, and the 465/466 have more comfortable seats than some 1st class seats….

I love the 313s, 314s, 507s, 508, and other PEP-derived units. They're beautiful trains.

Another plus point to the 717s that you omitted is the walk-through aspect, which does give them a good boost.
In defence of the 376s, they were deliberately built to be as spartan as possible because they are used primarily on routes through parts of south east London where, if there is anything on the train that can be broken, it will be broken. Likewise, they omitted end gangways between units to reduce opportunities for train-surfing.

319 needs a bit more credit. I also think 700s are not that aesthetically pleasing.

At the end of the day this list ranking is just a matter of opinion and personal taste. Or as I like to call it, everyone has their own favourite ice cream flavours. I've been travelling on the 507s and 508s since childhood, and they have served me very faithfully throughout my life. I even own a worksplate from unit 508202, originally 508105 under Merseyrail. It's gonna be a sad day for me when their time comes, all things must pass regardless if we like it or not. I tend to be more old school when it comes to my hobbies, especially railways. I love steam and BR traction, but I don't care much for today's modern stock.

My favourites on these list are the 507/508 and 334, I really like them. 319 was deserving of its spot though, horrible acceleration, dirty and unreliable.

1:44 almost jumped out my seat

See I get the fact that this video is made from a point of view in 2022, but when you consider the history of trains such as the 313s, of course I wasn't alive then but back in 1976 when they were introduced I'd imagine them to be incredibly modern trains with sliding doors and better seating etc. Considering they're almost 50 years old they're fairly reliable and well built trains. Anyway, this isn't me trying to argue, just pointing something out, I think this series has been brilliantly produced and edited, I'm about to go and watch the part 2 video now 🤣

The best of the EMUs are in the great rolling stock depot in the sky: classes 411/6, 421 and 415. Of current stock the 444 aren't bad, then 350 and some versions of 377.

318s are getting old but they still have good comfort

After this series, do a series of loco hauled sets

I'm on the fence about the Class 700. If you were to judge them as a train for metro services I think they're pretty good. I commute on them most days from zone 2 to zone 2 through central London and while I hate the ironing board seats, they are tolerable for 30 minutes. Everything else about them is a big upgrade over the the class 319 that ran on the route before. There's a lot more standing room, the air con is really good, the open gangways between carriages make it feel more spacious, the information screens are good, the windows are big.

But as a long distance train they're awful. For a London to Brighton journey I find the seats  painful, especially in one of the airline-style window seats.

I'm also a big fan of the 378, because I lived along the East London line when they were introduced and they're such a massive upgrade over the old tube stock that used to run the service. I think they're basically as long as they can be because of short platforms along the East London line that can't be extended, and in that case the longitudinal seating makes sense. I'm always grateful for the extra standing room any time I have to cram into one during rush hour.

While I do agree with the Class 507 and 508 as maybe looking a little bit odd as such, the comfort of them is definitely worth more than 2 in my opinion. When these trains were ordered, the Merseyrail network was owned by British Rail, hence the BR look and feel. The seats on the Merseyrail network I would say are quite good considering the use they get and how long they’ve had to live with passengers. I mean, I would say a 5 or 6. The 30-40 year old units will be replaced throughout the next 15 months by the Class 777 ‘Metro’ units, built like the Berlin U-BAHN.

Apart from this, I agree with most other comments about the other trains so for that, great video.

I like older electric trains and newer modern electric trains. And the older electric trains have amazing traction motors. Plus with the Class 465 and Class 466 Southeastern wants to replace them with new rolling stocks in the next couple years.

hope to see the 387 soon

Can't believe the 313 is last. I can understand the hate for them on the Coastway route, sitting on one for the long haul sucks but they're neat and have a good sound and decent interior. the 700 hate is valid, they're really good Except for the seats imho. but even with the seating they're great if you just use them for the core tunnel

The 334’s are not bad at all i use them everyday and they sound and look amazing and are very comfortable

i didnt expect the 313 in last place
personally i like them because of their sound but also thry used to run on my local route so there special to me

I can only speak personally, but I used to do Croydon to Brighton and back (45-60 mins each way) multiple times a week on class 700 trains and found the seats actually very fine.
