But it was still the middle of August on a railway that is resilient to all weathers. It appears you are advocating blanket closure or effective closure of the railway network after heavy rainfall (or indeed after any weather incident including wind or snow), which would certainly reduce the risk to railway staff and passengers. My point is that by making the railway that fickle will force passengers to use other less safe modes.

Nah, I'm not advocating anything, I really don't know what the answer is.  As you imply, there is a very complex set of considerations.

I was just making the point that a lot of people in the thread were focussing on the delay in securing the crossover, but it wasn't the delay that killed three people, it was hitting the landslide at 73mph.

Nobody wants an accident of any kind, but also nobody wants to have services routinely suspended or running at severely reduced speeds "just in case".

The train wasn't going to end up at its destination, and it was running on the only route open in central or eastern Scotland, and already had three identified locations on that route where there had been landslips or flooding.

That's far from "just in case".

The train was in no immediate danger while it waited for the crossover to be secured, and the fact it took 2 hours to secure the crossover isn't what caused the accident.

One of the areas on on-going investigation - and in my opinion, will be cited as a causal factor in the final report - is "the railway’s management systems and decision-making processes at times of wide-spread disruption caused by severe weather and/or multiple instances of infrastructure failure."

On the line, there had been two known landslips, and an area of flooding, with trains held at all three locations at the time 1T08 turned back.  Yet the train accelerated to 73mph.  As the report notes "as the signaller was not aware of any obstruction on the line, railway rules did not require him to instruct the driver to travel at a speed slower than the maximum normally permitted."

But common sense should have told the signaller and the driver that travelling at line speed was probably dangerous.

Would the accident have happened if 1T08 was turned back sooner?  Maybe, maybe not.  We don't know when the landslip it hit occurred.  But with a high certainty, the fatalities would have been avoided if the train was travelling at a lower speed.

I should make it clear I don't intend to blame either the driver or the signaller, nor ScotRail.  I'm just making the point that most people in this thread seem to be concentrating on the wrong thing.

To be clear, this is the interim report, and there are some things which are subject to ongoing investigation.

Lnerge, sorry for not replying sooner, I've only just seen this this morning!  That's a great photo, thanks for posting it!

I was there on the 1st April, and there was some work being done on the down branch, and it looks like a couple of the workers had spotted an issue with the left-most diamond in your photo.

What work was being done there?

I would really appreciate seeing more photos from that visit!

You skilfully predicted my next question!  Thanks, I will PM you, I’d like to get your point of view on something.  Thanks. 

A quick preview of what I’m been up to this week - one type of the Greater Manchester Waste Authority binliner containers.

There’s more fettling to do, especially around the door end of the container, and I’m sure I can make the final printed result much better.  This was printed with the support on the top of the container, which is why it looks so poor, and some of the walls were way too thin.
 

I’ll be doing a test print in OO tomorrow, this one is N.

Once it’s finished, I’ll be making the final model freely available in N, OO, and 1:1 so you can scale it yourself if required.

I couldn’t have created this without@pharrc20 and his photos, thanks Paul!

That print makes me very jealous.  I managed two 20’ containers on my Photon this evening!  I’ll join the Facebook group, thanks.

Are you open to sharing your 3D models, or are you offering them commercially?

Thanks,

Carl.

I'm looking for a larger printer, settled on the Elegoo Saturn, but they are like hen's teeth.

That is a tidy join though, if I saw that on a model, I'd assume it was a weld line.  Perhaps it's possible to divide the print up along the prototype weld lines?

At lot - certainly all the ones in my area - are just being infilled, so aren’t being either removed or replaced.  Presumably that saves a load on annual checks and maintenance, at the expense of a few wagons full of hardcore and a few hours effort.

Confusingly I've just tried again and it was much quicker. No excuses now, I'll have to give it a go. Well, apart from the lack of a baseboard to mount it on.

Please post a photo of it once you've printed it!

They look great, how do you go about glazing them?

The process is interesting for me, I need about a dozen portals and masts of various sizes for my layout, and a couple of signal gantries (on the WCML.)

£33/hr isn't bad really, especially if it's for an item you need multiple of.  I can imagine that mast, for someone familiar with CAD, wouldn't have taken long at all.

Pete raises an interesting point though - I guess ensuring the result is "good enough" comes down to both parties setting their expectations out when making the initial contact, especially the designer communicating the limits of the material or production method.

Relief of brick courses is hard - the desired effect is very personal, the modeller might not realise their preference, the designer might not know to ask, and could easily eat up a lot of time/money adjusting it after the fact.

Do you want to attach one of your .dxfs here, and I'll test with my installation?

Fools Gold - The Stone Roses

Hi,

That's interesting, it only takes a few seconds to import a .dxf for me.  If you continue to have problems, if you send me a .dxf, I could re-save it as a .f3d file to see if that works any better for you?

I printed the base for an AV7 turnout last night, but that didn't go quite as well!  I paused the print mid-way through to add more resin, and the layers after that point didn't adhere to the earlier ones for some reason.  I'll try again later, although I'll probably end up ordering one from Finetrax anyway since I need the chairs and the cast frog (if only to make it match my other points.)

Out of interest, if you don’t mind sharing, how much did that cost including the CAD?

Thanks Stovepipe, I did see that yesterday actually but didn’t think to add it to this thread!  I found it interesting because of the early concrete sleepers too.

Thanks Mike, I'll take a closer look at those.

Hello,

Which of the various KFA/PFA types available are best suited to the Greater Manchester binliner services from 2000-ish?  

None seem a great match to the photos on https://paul3715.tripod.com/binliner.htm, I think mainly due to the handbrake wheel.  I don't mind some modifications to make one of the Revolution types more accurate, but I don't know which one is best to start with.

Thanks,

Carl.

Annnnd it's assembled!  Is it perfect?  No!  Would I do things differently if I did it again?  Yes!  Am I proud of it?  Very much so.

There are a few little jobs to do before it's completely done :

- Slightly adjust a couple of the rails to ensure they meet optimally

- I need to clear up the little nubs off the chairs, where I cut them from the sprues

- Actually secure the chairs to the base

- Attach droppers (which in turn will secure the checkrails in place, a couple of them are a little loose.)

- Cut isolating gaps

Then I can stick it on the layout, and start laying the rest of the track on the scenic section ...

We continued this conversation over on this post here.  I've nearly finished constructing the junction with the chairs and rails, I'll post pictures over there when I'm done.

Hmm, interesting ...

OK, I need to up my game - that is quite remarkable!  As for whether to stick with 3D printing or milling, I was quite amazed at the fidelity of the print, and I think it's going to be sufficient.  It's only this one junction I need to custom build, everything else is on very high radius curves so I can use your regular track bases.

How did you produce the 3D file for your print above, I guess manually?

Either way, very impressive, and if I had the patience to model the chairs, I would probably give printing it a go.  (Especially since I need to order some FB chair sprues from you for a B8 base I have, as well as for my diamonds ...)
