When it comes to weight, the O scale models should weigh around 5.36 times the weight of the OO versions if just straight scaled up. This is due to the fact that O scale, at 7mm to the foot, is 1.75 times OO scale at 4mm to the foot, and being three dimensional objects that increase is cubed. Obviously Dapol haven't just taken their designs and made them larger, but it's still curious that both the Sentinel and the Terriers are less than that, and that the B4 is significantly above that. This is one of the many problems engineers face when using scale models to test designs. When the length of an object is halved, the area decreases by 4 times, and the volume by 8 times. This means a model of an A1 Terrier would have a 'scale' weight in OO of 63grams and in O just 339grams, which would represent an issue when pulling trains.

Can't get over the Boxhill Banana. It's even a yellowish colour! 😂

Sam you should make a video where you take a look at your fans layouts and give them a rating

Oh dear, the 00 Terrier looks like it's been in a collision - not just a bowed running plate, but the tanks and cab both lean in opposite directions...

Always nice when you upload something about o scale!

I really love your O Scale videos, really helped me get into the hobby and I’m from America so I’ve been really trying my best to get my hands on British locomotives. Which I bought from Hattons.

Hi Sam, a brilliant video, and I purchased a B4 O gauge DCC with sound after your review and is my one and only 0-4-0 locomotive, what a fantastic model. I don’t like Terriers and I have a Y3 in O gauge kit built that I inherited and is a good runner. I still purchase OO gauge so it was great to see your video on the comparisons. I do always fit crews to all my locos and oil lamps. 🚂👍😃🚂

Interesting comparison Sam. Perhaps what stands out the most for O are realistic couplings. We always find the couplers to be quite long and rather absurd in OO. For H0 they are at least short and neat but nowhere near real-life. In O they are genuinely authentic 🙂

Hi Sam me again, a tender locomotive in O gauge by Dapol it got to be a GWR City of Truro ( Duke Dog ) I don’t have one in any gauge, It’s time I did get one !

So, Sam... you need to buy an O Scale Flying Scotsman to compare the TT, OO, and O Scale versions... right? John BC, Canada

*Your Pokéloco has just evolved!*

Hi Sam I would like to see the C14 class produced by Dapol in 0 scale .

I've pre ordered black 5 with sound from Ellis Clarke 0 gauge will post when it arrives

U should compare dapols rolling stock lol I got some of the dapols oo scale vans and yikes those things can't stay on the ground if they tried too

If I was starting from scratch I'd go for 0 gauge, for my interest (branch lines and short trains) there's not much difference in price.

I'd be interested in a 121/122 or GWR bubble car comparison as well. I don't have many modern Dapol 4mm locos, only really a pair of 68s tbh, but I have a few more in 7mm. I really want a 7mm Manor from Dapol. I'm modelling a western region branch line, so I have a rule that says nothing larger than a Manor or a 37, excepting heavy freight steamers (like a 28xx or WD 8F). Except no one does a RTR Manor yet, and the heljan 37s are a bit above my current price range...

O gauge is beginning to attract me a lot with these lovely locos being a *lot* less than the new OO gauge releases. I may have to build a 12 x 2 end to end shunting or MPD layout just for the heck of it... I've handled a few hand made O gauge locos at my MRC and they are truly wonderful and I've aways lusted after that level of weight and gravitas... and the proper couplings lol - also at my age, I can see the detail better.

Dapol make the Terrier in 3 scales: O, OO and N. The N gauge one came first, followed by the O Gauge and then the OO.

Nice video, but I do wish you'd cover Dapol's N gauge models sometimes.

I would be interested to know whether the better selection of 0 gauge material also gives a better sound than 00 gauge?

Hey sam can you make a review about the prr t1 4-4-4-4 i just love this loco and would be so happy to see you review it even if its old😅

Decent video here Sam, although O scale,is nice I think for me I would be staying OO die to how much I have in OO gauge already, talking about that I received my heljan 10800 prototype locomotive and as I predicted it is an excellent model from them, need to still look for a terrier myself a really nice locomotive those are.

Good afternoon, Sam! Yet another great video from my favourite model railway reviewer. Fun fact! I have exactly one O gauge locomotive. It's an AHM Prussian 0-6-0t, in a quite inaccurate AT&SF livery. Speaking of my own model trains, I plan to buy a Mainline Collett Goods along with some rolling stock on Christmas.

They are just being smart, like Fleischmann and Roco. Both are the same company, only Fleischmann is N scale and Roco is H0, so they make each others locomotives and wagons in other scale. They just send each other the drawings and they change is so it fits in the scale. I think Depol is doing the same, and it's very smart of then.

The o gauge terrier loco is a work of art imho. Stunning.

Love to see your O scale locos. Cant wait to see what you add to your 0 scale Collection Next.

hey sam you should try t gauge and see how much/little it differs from tt and oo in stuff like detail

An O Scale Large Prairie would be awesome!

I’d say it’s the working couplings being standard in o scale that impresses me most. Only one manufacturer made working screw links in oo. I do hope to be the second to manufacture them sometime in the future. I’ll make sure you can buy them assembled though ;)

A few years ago you did a video on buying 2nd hand. Can you do an up to date version, perhaps making up different 2nd hand sets. Many modellers can't afford £250 for a set so 2nd hand is the main option....

Hello sam great video do you plan to look at the o gauge 57xx in the future

It is understandable that is is easier for a manufacturer to produce the same loco in two gauges rather than produce different models for each gauge. From the point of view of the collector, you don't really want the same loco in two sizes! It is a bit of a disappointment that all the new TT:120 stuff, is shrunk down versions of the old OO gauge stuff. Of all the gauges and scales, OO gauge is definitely the best scale. It is large enough to give detail and small enough not to require a huge room! Thanks for uploading.

12:54 is it just me Sam, or does the cab look like it's not fitted on properly. Lol Cheers Jasper & Willow

Hi Sam, just wondering if you're planning to review the new Accurascale Manor? It looks amazing and I'd love to see an in-depth comparison to the Dapol version before I buy one

You should review N scale locos too.

When will you do a vid on the new catalog?

What's inside ? O scale has a 9 pole motor ?

@SamsTrains did you get the interesting rail vehicle photos I e- mailed to you

When ar you doing the Accurascale manor

Hey there Sam, are going to review the new Accurascale GWR 7800 Manor Class on your channel soon?

Very good. Small O scale engines have struck me as providing reasonable value for money for a while now, providing you have an O gauge layout of course!

I think Dapol should make the beattie well tank in O gauge Sam. Although I wonder how much they would be. Cheers Jasper & Willow

Great video Sam! Very well done.

Great video, and nice idea for a comparison. For my own, I would be happy if Dapol does an OO version of their N scale 9F, Britannia class, and class 35 (I have them all in N). and a OO gronk by them would be great too ! They already have one in O, that would be easy for them...

Going by logic of "well if its big you may go gargantuan" Beyer Garett in 0 scale? or the exact opposite, get the smallest terrier you can find to go 0 scale. On THAT note i wonder, would mr. Sam's trains care to make larger scale model via his printers? maybe that could help with some detailing and in any ways would be amusing to see him wrestle with being thrown off his comffort zone scale, i reckon that is best way to improve - constantly challanging one's own craft to higher standard or unusual ideas. Slightly strange but amusing idea to review differences across scales on same model by same company. hopefully it trends upwards in quality over time as 3 are slightly too small example size, tho could show general trend.

Great video, and very enjoyable to watch. Reminded me of what my mum said (years ago) to my fiancee when I was taking her to a model railway show - 'You mustn't say "What a ducky little engine" ' ...

why have you not used your class 08?

Love seeing O scale Sam, but i would one day love to see you review some large/G scale locomotives 😄

Awesome video Sam's trains

The "Little baby Sentinel" bit was kinda offensive, you're gonna hurt the poor thing's feelings!

My favourite O Gauge model in your collection is the GWR Auto Tank Engine.

Prototype Deltic in O gauge 😊

Hi Sam

I haven’t seen your OO scale terrier in a while and I was absolutely blown away bow how warped the running board was. It was almost as if the locomotive was melting or sagging by the fire box, almost like a cartoon. (Perhaps a little too dramatic) but my point still stands! 😂

Hi Sam, great video. My little lad and i always look forward to an upload. Ive always been a OO modeller/collector and just puchased a Heljan class 60 in O gauge and 2x MGR wagons. The physical size of O makes me smile! Some of the inflated prices of OO compared to O im wondering if OO is expensive or O gauge is cheap?

Sam, thanks for making fascinating videos on model railway... Could you do a video on running a loco through fire. It sounds silly, but I can imagine it being really fun...

Excellent idea to compare the scales -- and if anything it shows how the growing popularity of 0 is forcing the 00 manufacturers to up their game in terms of detail in order to stay competitive. I have the 0 Gauge B4, and the cab on mine sits down perfectly right out of the box. You could try refitting the protruding nut, or maybe grind it down a little. I do think the LSWR green is a little too light in colour here, old photos show Adams 'holly green' goods livery much darker than the 'pea green'' passenger livery -- and indeed Dapol's own pre-production drawings show a dark green colour. But it's a beautiful beast anyway. As to ideas for Daopol's possible next combo, I'd really like to see them produce the Beyer 'Metropolitan' 4-4-0T -- especially now that we are getting really excellent 19th-century 4 and 6-wheel coaches to suit. Kits for these fascinating tank locos have been produced in both scales, but I think are now long out of production.

Interesting comparisons 🤔🚂🚂🚂

That running plate on the OO Terrier just ruins the whole look. It looks like it's broken in the middle. Not a good look for Rails' first exclusive.

I think one of the biggest differences between oo and o gauge which you failed to mention is that of the couplings! No massive protruding hooks on the O gauge 🤗 but, still a good video! Well done Sam

Hi Sam, interesting & fun. Always seemed to me that O is better value than OO (my gauge). I was shocked how bowed the oo terrier running plate is as I was thinking of getting one of the Rails in GWR livery. A win for Hornby at last?? Cheers as always.

Hi Sam, interesting idea behind this video... To answer your question regarding what should Dapol do in O? How about the new Hawthorn Leslie in O as well as the new OO model? Cheers

Why is your OO Terrier shaped like a Banana? lol

Fantastic video 😊👍🤩😎

Very interesting video today Sam I am looking forward to see what dapol has planned

Love to see the flying Scotsman in o scale.

Ace video Sam, I do enjoy the comparison videos.. Many thanks and we'll done... But which was your favourite out of the 00 scale locos...???

Great vid, very interesting comparisons. You got your.manor yet?

Day-pol not dappol!

I'm really surprised about the differences between the two scales Sam. For me it has to be the b4, I absolutely love those models Cheers Jasper & Willow

So amazing video

Hi Sam, Good review, Overall I would say good judgement , spot on, All the best Brian 😃

Interesting...👍🏼

I’ve got that Boxhill model! Is it a Locomotion Models exclusive? If so then that’s the exact one I’ve got!

Letting the drivers slip while doing a pulling test gives a false reading as moving friction is less than static friction.

Am I really First Sam. Lol

Make yourself a better man,SAM...JUST SAY NO.

Hello! (First)

Pin pls first comment!!

Try complaining about the prices ,and encourage people not to buy. Just stop buying and paying overblown prices for toys. The Chinese have got us by the throat now.Start low and end up high. Nearly 300 pounds or more for toys is unexceptionable. Put your money where your mouth is. JUST SAY NO
