Londontram Posted March 12, 2014 Share Posted March 12, 2014 (edited) It's a 3F at a quick glance to tell the differance a 4F has a raised "step" up over the cylinders on the running plate and front buffer beam in front of the smoke box where as the 3F is flat as you can see in these two photo's the first shows a 3F with a flat running plate and the second a 4F with the raised step Edited March 12, 2014 by Londontram 1 Link to post Share on other sites More sharing options...
Poor Old Bruce Posted March 12, 2014 Share Posted March 12, 2014 Very nice, but isn't this a 4F? 3Fs and 4Fs used similar sized boilers. The 4Fs were superheated so needed a longer smokebox while the 3Fs weren't and had a shorter smokebox. The 4Fs also had piston valves above the cylinders (the 3Fs had slide valves between the cylinders) which required the boiler to be pitched a bit higher.

LNWR18901910 Posted September 16, 2017 Share Posted September 16, 2017 I hope it runs well better than before. Unless, you had the recent Bachmann model of it... Link to post Share on other sites More sharing options...
LNWR18901910 Posted November 21, 2017 Share Posted November 21, 2017 It's a 3F at a quick glance to tell the differance a 4F has a raised "step" up over the cylinders on the running plate and front buffer beam in front of the smoke box where as the 3F is flat as you can see in these two photo's the first shows a 3F with a flat running plate and the second a 4F with the raised step Fascinating. You can really tell the difference. It's a shame that none of the 3Fs have survived. Link to post Share on other sites More sharing options...
DCB Posted November 22, 2017 Share Posted November 22, 2017 I hope it runs well better than before. Unless, you had the recent Bachmann model of it... The early 3Fs with non see through wheels and screwed together chassis can be made to run really nicely if fitted with Markits Romford wheels. Bushing the chassis and soldering the gear wheel to an axle bush and to a 1/8th axle makes a good solid job but the motor pokes into the cab. I plan to shorten an X04 by fitting super neo magnets at some stage for mine and with the screw together chassis the front weight can be shortened to leave a void between the frames which cutting away the under boiler skirtings would reveal.

PatB Posted November 22, 2017 Share Posted November 22, 2017 Say what you like about Triang (and their successors) but it can't be denied that, in their day, they were at the forefront of plastic injection moulding. That their products are still considered worthy of work and, given that work, produce quite decent models I think speaks volumes. Their biggest failing seems to have been to have made little progress post ~1965 or so, until Airfix/Palitoy/Lima (maybe not quite so much) gave them a big wake-up call in 1976 or so.

Graham456 Posted November 22, 2017 Share Posted November 22, 2017 No doubt some one could blast holes in these models. And will point out Bachman do a new and improved But the best thing is your haveing FUN and enjoyment doing this which is the most important thing Keep going and enjoy Modeling Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted November 22, 2017 Share Posted November 22, 2017 ... It's a shame that none of the 3Fs have survived. Or even something earlier yet from the Derby line of development: a Kirtley outside framed / Johnson round top boiler specimen actually survived working into BR ownership as no 58110, a design with its beginnings just twenty years after Stephenson's Rocket... Technically, the 4F is sufficient as the end of that development line. The British 0-6-0 format became pretty uniform early on, such that the preserved earlier specimens of various types between them enable one to chart the development path readily. No doubt some one could blast holes in these models... Or even did. Notably the H-D and Wrenn product would survive assault by air rifle, where the Triang bodies finished up shredded. (The Triang was much more fun, simply because bits flew off; and of course some cement could reassemble them somewhat.) The bodies were in fairly plentiful supply too, as kids without any suitable oil available wore the mechanisms out something awful... Link to post Share on other sites More sharing options...

Sandhole Posted June 24, 2018 Share Posted June 24, 2018 Morning all, Here are my two Old Ladies. I suppose these have had the Full Spon. Boiler modded, full Romfords, handrails etc. One has a modded Triang tender, the other an old Ratio tender. Both still have the excellent XO4 motor in them. The Deeley tender version has the origional worm and gear. I just love 'em to bits!!! 5 Link to post Share on other sites More sharing options...
timbowilts Posted June 24, 2018 Share Posted June 24, 2018 Very nice, but isn't this a 4F? No, it’s definitely a 3F. Triang never did a 4F Tim T Link to post Share on other sites More sharing options...

Steamport Southport Posted June 25, 2018 Share Posted June 25, 2018 Yes I think we have different requirements/expectations (which is fine). Very well put. We all like different things and if you are getting enjoyment from them it's a bonus. They're great for projects and for enhancing skills. I think I lost count of the amount of Class 31 and 37s I detailed back in the early to mid 1980s as a teenager. They were going for pennies as everyone wanted the newer versions. If you messed it up then you went to the model shop and bought another one. Personally, anything Triang or Hornby Dublo would be put on eBay or straight into the bin now unless it has sentimental value. I fail to see any reason to use what I now see as toys that haven't even been made for over fifty years. Jason 2 Link to post Share on other sites More sharing options...
