Different Scales Posted June 14, 2020 Share Posted June 14, 2020 Has anyone ever mixed the two scales? I was having a look at Rocco freight wagons and coal wagons, ive only got a small amount of 00 gauge locos and i dont want it to look so unrealistic if i was to purchase ho wagons for a oo gauge loco. would there be a big difference in the size compared to one another Link to comment Share on other sites More sharing options...

LCDR Posted June 14, 2020 Share Posted June 14, 2020 HO and OO trains will run happily on the same track, 16.5mm gauge. HO is 3.5 mm to 1 foot scale or 1:87. OO is 4mm to one foot scale or 1:76. Therefore models in HO are 7/8th of the size. of OO. 7/8th difference can be quite noticable. However HO models are usually of trains of the European mainland or USA which tend to be built to larger dimensions than those of the UK, and OO really only applies to UK outline models. UK outline models in HO are not common these were sold in the UK in the 1970s by Lima, and Playcraft but didn't sell well and were abandoned in 1980. HO models frequently use different couuplings to OO models so this can be a disadvantage, especially with older models where exchange of couplings is more difficult.

81F Posted June 14, 2020 Share Posted June 14, 2020 Alongside my mostly 00 collection I do have some HO. Some HO looks OK when placed next to OO while others do not. If mixing stock I would recommend trying to avoid too many changes in one train. For example I have a rake of Joeuf CIWL sleeping cars most of which have Paris-London destinations which I bought to make up a "Night Ferry" set but the combination with an 00 CCT or PMV just does not look right. I think the trouble is that the door heights are quite differeent as well as the roof heights. However, I suspect most of the sleeping cars may be to the British loading gauge as one of them has a taller roof and has different inscriptions (in German). However, some of my american Locos do not look too bad (Bachman santa Fe and Silvertown & Durago 2-8-0) when next to british outline freight wagons but the silvertown coaches look wrong when next to a british loco. However the loco that really looks wrong is my USAT 0-6-0T, but I am guessing that this was built to the British loading gauge. I also have som Elecrotren 0-6-0T which look fine against most British stock (as they seem reminician of the small locos found in industry - indeed some have been produced in NCB Taff Vale and GWR livery!). Also I believe the prototypes operate on a broader gauge than standard so they would be generally wider than Standard gauge locos. I would also add that the buffers on HO locos (if fitted are closer together. I'll try to takesome pictures to illustrate. Link to comment Share on other sites More sharing options...
JJ73 Posted June 15, 2020 Share Posted June 15, 2020 I have a mixture of H0 & 00 Loco's - it has never bothered me - My 2 blue Lima Plymouth Switchers are H0 but doesn't mean that they are smaller!!! - See photos... /media/tinymce_upload/2ce337f2877d7a69bbc56acea33b52ae.JPG Out of 4 of these Locos - 2 are 'HO' & 2 are '00' - the Blue Plymouth Switcher & the Electronren are both 'H0' & the Cock 'O The North & the Class 4P No. 42334 are both '00'!!! & so sometimes '00' can be smaller & 'HO' can be bigger!!! Now that's confused you I bet!!! 😉 😀 /media/tinymce_upload/969ed8fc78753edf87f1de56d8cdeead.JPG Link to comment Share on other sites More sharing options...
The Doc Posted June 15, 2020 Share Posted June 15, 2020 Continental and US (in particular) locos and rolling stock are generally much bigger than their UK equivalents in real life, so an HO model can look okay side by side with UK 00 models if you don't mind the different styles (and couplings, as mentioned above). However, UK HO scale models such as the Lima class 33 and Mk1 and Mk2 coaches (no longer made - but you can still buy HO scale continental versions of the class 66 and class 08 diesels) look very small alongside their 00 versions. Then again, the Terrier 0-6-0 in 00 gauge looks equally small! I own a few Jouef and Fleischmann locos and they don't look small alongside UK models.

Sailbadthesinner Posted June 15, 2020 Share Posted June 15, 2020 The linear scales are OO, 1:76 and 1:87 for HO so HO dimensions will be 12.5% smaller. but the volume changes with the cube of the scale, HO will be 33% less volume so for the same model they do look a lot smaller.Some models, especially scenic stuff, is actually modelled at about 1:80 and sold into both markets. It all depends on what you are comparing against and how fastidious you are about accuracy.Remember rule 1; your layout, your rules. Link to comment Share on other sites More sharing options...
