The Shapeways models are looking very good. The Schoma diesel picture shows just how badly out of scale the signal post and bracket runs are. Bracket run maybe; have you seen some of the new signal posts? They're built to withstand an earthquake.  |

Bracket run maybe; have you seen some of the new signal posts? They're built to withstand an earthquake. Looking at the image and assuming the Schoma to be built to tube loading gauge the signal head is surely too low for an open section and the post itself would appear to have a scale diameter greater than one foot, I'd suggest strong enough to carry a floodlight fitting 50 feet or more off the ground. Next you'll be telling me that the ladder is not too wide, my recollection is that no rung was wide enough for two booted feet to stand upon simultaneously. Anyway if that's a 'modern' signal post where are the hoops and the safe working platform? |

Good point; you'd be shocked at some of the structures we have had built these days for signals!

Good sighting! I bet nobody SPADed on that. Seriously, you can only (properly) see the green aspect, and you could only move if that was showing. As for the next signal...

Hi everyone ! Sorry for the long delay in answering here, I've been quite busy with my university exams, and now my placement As for the size and prototypes,they come for various places : the LU rolling stock datasheet for some (although the drawings accuracy varies quite a lot from a stock to another), technical drawings John sends me, and of course quite a lot of pictures, from me of my old friend Google. As for the sketchup models, I'll ask john, but I doubt the models would be fit for a simulator, though, as there are some model-only details, probably way too much polygons, and out-of-scale wall thickness (to make them thick enough for printing). I had started doing a simulator-oriented 95TS cab, though, so I might try to finish it. I think John does, indeed, plan to sell the Schöma as well. I'll confirm you that information ASAP. As for the older stocks, I don't see why I wouldn't do them. For the moment, I don't have much time, but I'll be on holidays in two weeks time, so I should be able to model again ! Finaly, I do agree that 73 & 83TS should be available as 3-car train. I'll ask John  |

Really looking forward to getting some 72 mkII's to run on my Jubilee/Bakerloo layout. Any idea when ready?

Hey everyone! It's been quite a while since I last came here, but I though I'd share the latest model I'm working on. I've been doing this S-Stock mostly because I like this train, but I think John might try to produce it too. It's not quite finished, and the colours are awful (I just added them to get a vague idea of the look once printed).  |

That looks absolutely stunning A lot better than my attempts at the S stock that's for sure especially around the roof area on the cab. I'm just curious how you're planning to do the chassis/running gear? Cheers, Jon |

As for the chassis, it's equipped with the same system as the other stocks I designed for John: holding bars and plots inside that can fit a flat wooden chassis. I'll probably do the bogie side details later too, once we can come up with a 3d-printed prototype that I can work on. I'll keep you posted!  In the meantime, I've been working on R stocks (and Co/Cp too, quite similar)  [Edit]: I forgot to mention: I'll be at the Acton Town depot exhibition with John if anyone wants to drop by and discuss those models (or anything else for that matter ). |

Brilliant, you'll soon put Hornby out of business! Re the R & CO/CP I think the window layouts of the R were slightly different to the original O & Ps? Well Done John T |

There seem to be two different layouts… on both stocks! Some cars have two larger windows between the two main doors, while some have those four smaller windows (and different length on either sides of the two main doors). I try to model both, but I suspect there are other differences I didn't spot, so i'm still haunting flickr of detailed pictures   |

Thanks a lot for this! The gallery will definitely be helpful when designing the remaining parts (including the bogies) I'm in the process of designing the bogies for the S Stock too… Is it just an impression, or does it actually have much smaller wheels than other subsurface stock (except the D, which shares those with the 83 stock IIRC)? |

It's a large format with some side on photos showing the differences between the P & R stocks, and detailed photos of the interiors Regards John T |

The S stock does have smaller wheels which is why the ride is very average for a modern train. Probably best to use 10.5mm wheels for it.

Thanks a lot for those pieces of information! I'll try to get ahold of the book, and the wheel sizes will be quite helpful for bogie design! metman, Looking forward to meet you at Acton, then |

R38 Stock driving cars had the same window layout as COP and Q Stock (as they were converted Q38 cars). The later 'new' build cars, R47 R49 R59 had the wide 2 window layout. R38 being almost, but not quite, all the driving cars. Six cars of R49 stock were built as driving cars so that two all-aluminium trains could be formed - in those days District Line trains were formed of three single-ended units 4+2+2 so that they could run as sicx-or eight car trains. There are several pictures of one of those cars (with the faint "V" on the front) in the set attached to the earlier email. All the non-driving cars were new-build (R47/49/59). |

So, if I understand everything correctly… - R Stock DMs : Most of them had 4 windows, only a few had 2 larger ones - R Stock Trailers: All of them had 2 larger windows And for the Co/Cp : - Co/Cp DMs : All with 4 windows - Co/Cp Trailers: All with 4 windows. Were the Co/Cp trailers mixed with R ones sometimes? or is it impossible to have a 2-window trailer on a Co/Cp unit? Thanks for all this help anyway! |

There were no R stock trailers - they were NDMs. And my understanding is that R stock was incompatible with earlier types - the ex-q stock trailers which became R38 stock DMs had all-new electrical equipment - only the bodies were re-used. |

Just to clear it up for you: The R stock was formed of 6 or 8 cars (7 cars after 1971, but the formations got complex!) and all cars were powered so technically there were no trailers only DM, NDM and (U)NDM. I've put the 'U' for uncoupling in brackets as unlike the later 1938, 49, 72, 73 etc UNDM the R stock cars did not have a shunt control fitted. Very comprehensive! I've printed it out for future reference. How did a (U)NDM differ from an NDM, if it didn't have the vestigial controls fitted? I always thought the control cupboard was the difference. |

How did a (U)NDM differ from an NDM, if it didn't have the vestigial controls fitted? I always thought the control cupboard was the difference. As I recall, the couplings within a unit were permanent bar couplings. The outer ends of the UNDMs, and the DMs on the east-facing two-car sets, had autocouplers so that a six car could become an eight car or vice versa during normal service.(They were "handed", so the NDM of a 2 car set could not couple back to back with another 2 car set, but only with the DM of a 2 car set or with the NDM of a 4car. The DMs on the west-facing four car units would never be coupled to anything else in ordinary service, so only had emergency couplers (like the 3-car 1972 stock or the single-ended units of 1973 stock). Any shunting of a lone 2car set would have to be done from the driving cab, with a lookout at the NDM. |
