Model Forum / General / Railroads / May 2006which would look smaller - oo or ho?
Given two models of the same prototype engine, which would actually look smaller? Sorry if this sounds pretty basic, but I suspect a model I bought on ebay may actually be HO if that is actually the smaller scale - I know they are both the same gauge.

HO would be the smaller; it is approximately 7/8ths the scale of OO. John. > Given two models of the same prototype engine, which would actually look > smaller?

An HO model would be smaller. What is it a model of?

Yes. >PhilD > >> The crossing was famous, over the GWR main line. > > > >... and didn't the Lee Moor technically have right of way, it being > >there before the GWR line was? I explored what little was left of the Lee Moor Tramway in about 1968 when I was at college in Plymouth. Apparently for years after they'd stopped using it - or at least the lower section- they used to run one horse and wagon over it every year to maintain the right of way. I also seem to remember that the crossing had been slightly strange in that the GWR rail was unbroken and the wheels of the tramway wagons ran over the rail head with a break in its own rail which was slightly proud of that of the GWR. The crossing was at about 20-30 degrees so with judicious checkrails it is doable and I think some town trams did something similar when crossing main line railways. Part of the route including the incline planes was used for the pipes carrying china clay slurry down from the quarries. The route of the tramway's other line to Dartmoor was quite visible as stone sleepers though the last part to Princetown from Yelverton had been used by the GWR for their branch. >>>Ditto the Redruth and Chasewater in Cornwall: a very appealing modelling >>>project, that one (so's the Padarn, of course, with the transporter wagons [quoted text clipped - 8 lines] >Crossover: two points arranged to allow a train to move from one of a >pair of parallel tracks to another. ITHM a flat crossing. The Redruth and Chasewater had one of these, too, with the Hayle Railway.

I'm pretty sure - as a flip-side to the question about 4mm scale/gauge combos - that in 3.5mm scale, the EM gauge track used by 4mm modellers is a good approximation for the Irish 5'3" gauge.

The village does, but the railway (opened in 1825 or so) used the "S" spelling - presumably the spelling for the village name hadn't finally settled then. >I'm pretty sure - as a flip-side to the question about 4mm scale/gauge >combos - that in 3.5mm scale, the EM gauge track used by 4mm modellers >is a good approximation for the Irish 5'3" gauge.

Coventry certainly did till the tramway was destroyed in 1940. The 3ft 5in tramcars also had distinctive open balconies as demanded by the Home Office and rigid four-wheel chassis.

IIRC Bradford had through trams to Leeds, which would be fun to model, as Bradfod was on the 4' gauge and Leeds on 4'8.5". "Gauge Narrows" sign, anyone? Tim > IIRC Bradford had through trams to Leeds, which would be fun to model, > as Bradfod was on the 4' gauge and Leeds on 4'8.5". Hmmm? I don't recall through trams between the two, although I do remember travelling on a Bradford trolleybus which overran the overhead at its terminus. I suspect the driver wasn't too well thought of for that incident, although I doubt it was a rare occurrence. John. >> IIRC Bradford had through trams to Leeds, which would be fun to >> model, as Bradfod was on the 4' gauge and Leeds on 4'8.5". [quoted text clipped - 4 lines] > thought of for that incident, although I doubt it was a rare > occurrence. It was before your time, or mine, John. I rode the trolleys to school in Bradford in the early 1950s. There was a large turning circle on Thornton Road that had fairy lights strung so that drivers could follow the wires in fog or darkness. Huddersfield had a trolleybus turntable cantilevered over a cliff. I wouldn't like to overrun that one! SignatureMartin S. >>>>>Not in use, but I've read that there was in industrial line in Wigan >>>>>at something around 4' 1.5" gauge. [quoted text clipped - 9 lines] > > "Gauge Narrows" sign, anyone? Yes, there was a gauge transition in either Dewsbury or Pudsey. The wheels were unlocked and allowed to slide along the axles, then relocked. I remember the "Tram Pinch" signs in Leeds. Blackburn also had 4' gauge. SignatureMartin S. Hi: Here's some info from part of a scale and gauge spreadsheet I've been adding to. Hope this is of some use.

SignatureRegards Kevin Martin To reply - delete what is "not required" (Abbrev) Whilst the 5ft.3 inch (1600mm) gauge is correctly called Irish gauge, it is doubtful if that term is used in other parts of the world that use that gauge. Here in Victoria and in South Australia, 1600mm gauge is always called 'broad gauge' and I've never heard anyone, modeller, rail fan or railway man refer to it as 'Irish gauge'. The only other place that I know of to use this gauge is Brazil, and I suspect that there, too, it is called 'broad gauge'.
