'Shocked' seems a bit strong - TT:120 is just a scale like any other. Are you even more shocked by H0 given that 1:87 seems closer to 1:100 than even TT:120 does, never mind TT:120 to N Gauge? I doubt it. With the advent of TT:120, UK modellers now have a choice of scales of 2mm, 2.5mm, 3mm, 3.5mm and 4mm (as well as scales outside that range) - on the face of it there doesn't seem to be much to choose between any of them. It seems a bit strange to single out 2.5mm as being too close to 2mm when others are equally close. As for your closing paragraph, why even mention that here? This is a TT:120 thread. Do you go posting that on 00 gauge threads? Again, I doubt it. I'm sure there are plenty of other threads where those things are discussed.

I'm not sure what you're trying to say here, really, apart from the fact that 1/100 is an international architectural modelling scale. Just like TT:120 is an international model railway scale, whereas TT3/TT100 isn't. In fact, AFAIAA it is so international that the rest of the world just calls it 'TT' whereas we are forced to call it 'TT:120'.

Quite easy when you're dealing with whole numbers of feet I guess but I imagine it gets tedious if you're having to include odd inches and fractions of inches (and maybe yards) and then you're having to convert lots of measurements for a wagon or a loco or something...

I was just making the point that it is easier to divide by 100 than it is to divide by 76 or 87 or 43.5 or whatever, regardless of the units that the original drawings are in. That's why I spent my life working with computers - they are much better at sums than I am.

I freely admit I'm rubbish at sums and on reflection something in TT100 might be only 42% bigger by volume than the same thing in TT:120. Even so, 42% is still a fair difference. I'm sure that someone better than me can get the right figure!

I know you are just expressing a personal opinion, but you don't say whether the 3mm layout that you saw was running on 12mm or 14.2mm gauge track but if it was 12mm gauge then surely the rolling stock was over gauge which would contribute to its apparent bulk, giving the wrong impression when you look at something like TT:120 that has the correct gauge-to-scale ratio - just as it would when comparing British H0 to British 00. And just as a model in TT:120 is almost twice the volume of the same model in 2mm scale, then something in TT100 is going to be around 60% bigger than the same thing in TT:120, so no surprise that TT:120 looks a fair bit smaller than TT100. As for scale, that is just a ratio of the size of a model to the size of the real thing - I can't see how there is anything psychological about it apart from some people having a preference for bigger scales and others for smaller ones. And surely there is nothing intrinsically special about architect's scale being 1:100 - it is simply easier to divide a measurement by 100 if you're making a model, which is nice for TT100 but it isn't an insurmountable problem in other scales.

My four BG Mk3 coaches arrived yesterday - I had to delay the DPD delivery by 8 days because I was away on hols ☹️ but today I finally got the chance to play with them check them and test them. I think they look great. I can't comment on the prototypical accuracy but then that doesn't bother me as long as they 'look right' from normal viewing distances. The running qualities are excellent in both directions - i.e. both when pulling and pushing - although so far I have only tried a loop of track so no points to date. But I'm relieved that I don't have the wheel binding issues reported earlier. The only initial 'problems' were a couple unplanned separations between coaches. Inspection with a magnifying headset (those couplings are so tiny!) showed that, once the couplings were correctly aligned, sometimes both metal hooks remained raised rather than dropping down and locking onto the opposing coupling. A light touch with a screwdriver dropped the hooks into position. A bit of running in might fix this but I'll probably fit magnetic couplings when I get around to it. I might wait and see what the proposed Hornby ones look like before I decide which ones to buy. I'm very happy and I'm looking forward to the Class 50s and the Mk2F coaches! EDIT: apologies for the phone-camera blurry photo!

I watched it last night and I quite enjoyed it. I thought they were pretty open about the issues that were discussed. That is good because if anyone is suffering from any of the running problems mentioned then it could point a way to a potential fix. For me, I think I may need to take a look at the insides of the axle boxes of my 12T tank wagons - but I think that's about the only problem I've had so far. Touch wood! Also good to know that issues are being investigated and addressed when they are discovered. The exchanges about the design/development/production schedules were also interesting and also that they're not sticking rigidly to the original plan - as we've seen with the J50. My take on it was that they're keeping an eye on whether steam or modern image is selling better and they may further adjust the release schedule to suit. I wasn't sure what to read into Martyn Weaver's body language at times, though - he occasionally seemed a bit fidgety - I'm sure that should mean something! 😆

True to form for Hornby's logistics company (CCL ?), despite all four emails arriving within about an hour of each other last Friday, I've just noticed that three of my Mk3 carriages are showing as 'Dispatched' with a date of today (the 15th), but the Buffet is still showing as 'Processing'. I guess I should have known better than to expect all four to arrive in the same package... or at least, on the same day.

That image is probably a couple of 00 scale locos because Hornby didn't even have a complete TT:120 loco available to show on the Q&A - IIRC all they had was a couple of recently-received test mouldings that they hadn't even had time to assemble. I don't know for sure but I suspect that the front coupling on the 00 is optional/removable (at least, I think I've seen this on other 00 models) and that's possibly why they didn't put it on the photoshopped images they're using for the TT:120 models.

I noticed that as well - my HST arrived on 22nd March but the points don't appear to have been credited yet. Hopefully we're on the cusp so fingers crossed for next week, although I'm fortunate in that all my pre-orders are already in so I don't have anything I want to buy (at the current time 🤔) therefore I can afford to wait in any case. I might be waiting on the Class 37 before I spend mine! I must resist the J50...!

I was originally charged p&p on each one - each carriage was a separate order (in spite of ordering all four at the same time) and as there was only one of each carriage then each order was under £50 and so each one attracted p&p (I hope that makes sense!) I'll be contacting Hornby about the p&p after the carriages arrive. I didn't think it worth doing beforehand because I think you only get the p&p back on ones that arrive on the same day. So if (for example) all four were to arrive on different days then from what I've read I don't think they'd refund any p&p in that instance.

A couple of hours ago I received four emails saying that my four BG Mk3 pre-orders have arrived. My credit card has been debited as well.

Mine are quite tidy - I have 10 devices between 192.168.0.10 and 192.168.0.27

Thanks for that reply - that sounds like a practical and sensible approach. I've just switched on every device in the house I can think of (except the Z21, which is boxed up atm) and a quick check of my hub shows that there are 10 devices connected so I don't think I'm going to worry about it for the time being.
