What is the difference between oo and ho scale




















The Norfolk and Western streamlined passenger locomotive, the J-class ,has just completed it's restoration, and I have watched it pass my house twice, and rode behind her on an all-day excursion on June Hundreds, maybe thousands of people lined the tracks as she went through my town, pretty much GASPING at her monstrous presence me included!

She is as tall as 2-story house. On my layout, my A4's and my J-class are the same size! Now everything is just "out of whack" on my layout I think we have talked about this before, but it all seemed to start very much by accident. Now German locos are similar in proportion to US ones, and it wasn't possible to squeeze a British outline loco round it without major distortion. However it worked out OK if a larger scale was chosen. When Hornby started making Dublo in they followed this convention, because their early motors contained a massive horseshoe magnet which would not fit inside a British HO body either.

Or in their case the plastic was moulded! A few manufacturers have sought to take advantage of more modern compact mechanisms, and make HO British trains but with little real success. I can think of four companies that have tried. Lima, Joueff, Rivarossi and Fleichmann. All these are mainland Europe based you will notice. It seems that few British enthusiasts were prepared to make the switch to HO.

Trix actually used a compromise scale 3. Sad really because some of their later models were quite good. The opposite held true with some of the Kitmaster loco kits. Set alongside normal OO models they tower above them. I do have some British HO, but it is a very limited selection. One strange casualty of this was the Lima Class It was originally planned to be a HO model, and the bogies were tooled in HO scale.

However the body was tooled in 4mm scale but Lima put them both together. Look closely and they look VERY odd.

Posted at Sat 20 Jun There are still a lot of HO Lima 33s about so buyer beware. The continental type coupling is a clue BUT unscruulous ebay sellers can hide them or 'photoshop' these off the picture. The HO loco was only available in blue. Lima also made HO scale Mark 1 and Mark 2 coaches to go with the Also green versions. Posted at Mon 3 Apr Well Lima produced the class 33 in HO with both types of couplings continental loop and Triang tension lock espescially before changing over to Many vendors are not necessarily experts as they are trying to get rid of trains they lost interest in.

If it is 20mm it is HO if nearer to 23mm it is likely OO This is unambiguous! Of course all over Europe both sides of the Channel buffers are the same distance, even in broad gauge Spain and Russia! Posted at Wed 5 Apr Posted at Thu 6 Apr Well they do turn up on e-Bay for a song.

The OO scale models are built to th scale while the HO scale models are built to th scale. In simple terms, if you were to push 87 HO scale modes together, the result would be the same size as the real deal. Likewise, if you were to cram 76 OO scale models together, the final form would be the same size as the actual train.

We should mention here that you can use HO and OO scale models at the same time. Because they both use the same track gauge Whether you are handling rolling stock, locomotives, tracks, or the copious accessories, you won't hit any roadblocks.

Having said this, the correct scale for the When you use the OO scale with the Below, you can find two tables that set out the differences between them in an "at a glance" format. Perfect for those of you who are getting into this fulfilling hobby.

The cars were also cast metal and I believe they made only a boxcar, hopper, tank car, and caboose, in each case, detailed some had brake cylinders and the cabeese had smoke jacks and "semi-detailed" versions for a total of 18 different cars issued, each with a couple different road names. A wee bit more to the story. Different couplers were used by different mfrs. Few, if any, are compatible. Europe is HO and uses different couplers again. Shortliner Jack away in the Highlands. OO that uses However things used to be where each continental manufacturer did its own thing in the scale gauge ratio.

Fleischmann went from to and on to I live in Canada where we have volt house current as opposed to the volts used in Britain. I use a lot of British made electrical items with 16 volt AC input such as controllers with back EMF for more constant speed operation.
