The Survey Inspection Device (Sid) was initially conceived as a locomotive-mounted unit, but subsequently developed into an autonomous vehicle to minimise stopping distances. Sid runs ahead of a train, relaying images to the cab of the locomotive. The vehicle can also measure track profile and is equipped with CSIR's Coricam multispectral camera. In addition, CSIR says Sid will be able to carry out inspections of overhead catenary, while image recognition will enable the vehicle to detect stray objects or trespassers on the track and automatically alert staff. The vehicle weighs around 450kg with all systems onboard. CSIR says initial tests of the vehicle on the Transnet network have been successful and Transnet is now funding industrialisation of the concept.



That's and interesting concept. I don't know how the FRA would allow such a thing.

Interesting, but how does one move that things around when not in scout mode? (I see no couplers!)

What kind of facilities does it need for maintenance, does a normal locomotive workshop suffice or must there be a special facility just for the SIDs? How are these assigned to trains, based more on tranck inspection schedule or accident frequency?

At the same time both amazed that I haven't heard of such a concept before and also wondering all the possible reasons why the railways would want to manage without. It would need to be very autonomous and very low maintenance to not to cost more than its perceived benefits.


Another thing.. if this thing is atonomusly leading a locomotive does it trigger blocks or is it like a speeder and invisible to track circuits.

If its like a speeder it could end up at a interlocking before the train does and it could pass through before a route is lined and end up going a different way then the train.

South African Railways (SAR) GMA class Garratt heads a freight north of Vryburg on the line from Warrenton to Mafeking in August 1982. At this time GMA's were replacing 19D's on most of the traffic avoiding the need for double heading. Class 25's were also seeing their first regular work on the line.

> All hail the not-free market!
Wait, what? Do you know how costly it is to operate steam locos in small numbers? This is completely a heritage fleet to cover touristic trains and thematic events like veteran trains and locomotive parades, sometimes renting the engines for filmmakers.

Steam engines at the light freight work or shunting are usually just to prevent them and the personnel from being too underemployed.


So what's wrong with my statement? I meant profits from touristic trains clearly can't cover all costs.
Here's the operator, btw

Nothing, I was thinking of another thing apparently.

Still not sure if they really can't cover all costs just with tours and filmmakers or the actual train work is here just to squeeze more money. If first, clearly there have to be some subsidies from RZD or some state institution. I doubt it all can recoup the cost of rebuilding each of these engines basically from just a frame.

Where has the urban rail thread gone?

Ah well.
So heah, Länsimetro opened today: https://www.youtube.com/watch?v=9zGvhYRgBBE

They had the student orchestra to delight the early morning visitors, of whom there wandered a reasonable number, everyone thinking they'd be almost alone. Later the day very small coffee, cake slice, bag and mug ceremony. As it's saturday, some probably use the new instrument for bar crawl right away.

So yeah, urban rail - the armchair foamer's rail. Always things happening.

Heck yeah Suomi-Russian thread!
Don't know the numbers, but in my home city there are curves that don't even allow to have full sized left-side mirrors on the older cars (pic related, look at this little shit), so there's no reserve at all. But that system is screwed up anyway so nobody would let decent modern cars on it before reconstruction.
Forget the memetram, it's gone. RIP

>they are made by Tver Carriage Works, which belongs to Transmashholding
Again, mostly wrong:
the model is created by PK Transportnye Sistemy (PK TS) and produced in cooperation with Transmashholding on its Tver carriage works - both companies are based in Russia.
Formally the contract is signed via Metrovagonmash, which is another TMH facility, so in its essence this is true, the TMH is playing the role of a safeguard in case something happens with PK TS. Ooooor TMH just wants to lay their hands on their business some time in the future:)

>Can you give typical Russian numbers btw?

You know, I think you do not quite get that 3-unit tram on rotational bogies should have smaller dynamical "footprint" than one long single-unit car. The main limiting factors are the bogies themselves and the frontal and read overhangs (which are mostly known for creating clearance issues). Anyway, the only loading gauge numbers I could find are minimum 1675 mm between closest rails of neighbouring tracks and no less than 2026 mm with poles inbetween (suddenly realized this is an extremely uncommon thing for Moscow tram, if any such stretches exist).

And yes, Vityaz has a minimum curve radius of 16 m which is, I take it, the absolute minimum for all modern trams.

Oh no, so much for my monopoly:) Anyway, greetings, comrade! Let's hope this site can handle more than one Russian… there is some history…

>my home city

<Insert Podzemniy Perehod Imeni Pushkina joke here> Anyway, I hope your authorities will have enough brains to order some used KTM-19* trams from Moscow as they are starting to give them away, basically for free. These are still superior to 70% of rolling stock in an average Russian tram city.

>curves that don't even allow to have full sized left-side mirrors

That's the overhang problem. Probably someone screwed the approach gauge so it is too tight to handle (relatively) modern trams with their huge overhangs.

The Moscow's Imeni Apakova depot is infamous for this problem. Turns out they can't handle anything newer than KTM-19 series AND (this is kinda ridiculous) they can't even fix this problem because the depot is under state protection as a historical building so they can't rebuild anything. The latest rumors are that they are going to arrange new site on the south of the network which could handle new rolling stock.

This is what should be noted by our Finnish friend, despite not being able to handle even single-unit KTM-23s, Apakova somehow fits an ENORMOUS 8-axle KT3R Cobra tram (a joint experiment of Czech PARS NOVA and Moscow's Tram Repair Works). Here. Aint she pretty?

Privet. I've been visiting this place from time to time for a while though.
>order some used KTM-19* trams from Moscow
They couldn't find money to transport the cars at first lol. Then they managed to get five 71-608КМ's. And one body of Stadler (actually BKM) 62103 to put it on top of the old chassis, picrel.

Bet they still have the money for a bunch of SUVs with enough horsepower to haul the trailers with those cars all the way to Omsk :D


As for meme tram aka Russia One, it is indeed done. And it was destined to eventually flop, apparently. Hailed as "the chosen one" which should bring balance to the Russian tram engineering it was in fact almost in every way inferior to the humble Vityaz which was already a fully working prototype while the R1 was just a 1:1 model with no running gear. It is actually surprising that the widely known reason for closing the project is that they didn't came up with the running gear despite previously it is said that it should've been on the bogies of the 71-409 model.

…which are not rotating which is the main drawback for such massive tram.
And THIS is why it is quite surprising to hear it can do 16 meters. I mean, this design could've been fine for systems with only, like, 100-meter curves and smoother, but 16 meters with non-rotating bogies and such massive units?

Well maybe they decided to rethink this tram for rotating bogies and failed. Anyway, it's demise also was very strange as for about two or three years there were no word of the project except some officials one said that "it is too expensive to even try to sell it within Russia so we will assemble those outside of Russia for ONLY foreign customers". If it sounds gibberish that's because it is. Whoever said this, this guy is terrible in excuses.

Oh well, at least we have well in production, superior and also quite stylish Vityaz-M so overall Russian tram engineering is currently doing fine without "the chosen one". Still I hope UTM will come up with something competitive eventually.

There were horse-drawn carriages still operating in the late 19th to early 20th Centuries. Henry Ford's "Jew-Flattening Machine" (pic related) wasn't in widespread use yet; at least not in that game.

As for train grades, like I said a few posts up, track place is reminiscent of "Sid Meier's Railroads". Though I'm not sure yet how that would affect the operation of the trains in-game, since I'm only at the part where I'm helping Thomas Clarke Durant lay out the Union Pacific's half of the Transcontinental Railroad.

Early skyscrapers? The game probably has enough lattitude to where one's rail line can have such an effect on the economy that office towers and other such could be built.

I guess it all falls back on the old line, "It's just a video game."


Oh I know, I just had to poke some fun at the game.


File: 1518384455317.jpg (126.9 KB, 1200x675, 068677.jpg)

I did find out that "Railway Empire" does bitch at you for using a locomotive on a line with a higher grade than it can handle with the load it carries.

Though one thing that "Railway Empire" has that neither Meier nor Sawyer have implemented in related games, is a tech tree (pic related). Not just investing research points in locomotives themselves, but on mechanics and technology.


Are you enjoying it so far?

I really want to get it but it's more money than I can spend at the moment.



It's a ball-breaker. But I'm determined to enjoy it. It's been a time-sink.

In 1980 film Reds the tram was played by an Anerican too, a 1920 Brill.

(The trailer was a 1916 Asea.)


A ship can also have a caboose. This is when they galley is in a deck-mounted cabin.

As a result of it being installed the regular signals had been suspended. If they had been working this could have been avoided.


There are dozens, maybe hundreds, of territories in the US that run "dark" with no signals even installed. The CSX dispatcher was issuing their equivalent of track warrants, and had proper blocks set up to separate trains. It was solely the failure of a crew on the ground to make sure that the switch wasn't left open. Depending on the type of signals they had, it might not have even made a difference regardless.



If they had been running regular CTC, I would imagine that that switch being open would have dropped the signal and Amtrak would have been talked by, and run at restricted speed until they saw the bad iron.

Even with ABS that would have been the case. A red there would be stop and proceed at restricted speed, and then they would have found the bad iron.

Yeah, Murphy's Law that this happened during a signal outage in support of a PTC signal cutover. Still though every incident has multiple failures contributing to it. Will be interesting to see the final NTSB report in a few years.

Also will be interesting to see what happens to the Amfleet II cafe fleet. These are some of the highest millage cars Amtrak has on the east coast. Wondering if material fatigue is beginning to set in for these cars.

Acela Express trainset separates at speed. 52 passengers aboard; no reported injuries.



This only seems newsworthy because of the recent fatal crashes. Trains separate all the time. Admittedly, most of them aren't travelling at high speeds while full of passengers, but still.


Still not a good look for the closest thing that Murrica has to HST.


"All the time" is a bit of an exaggeration, but fatigue in knuckles should be caught normally, and good train handling should prevent it, though shit does sometimes just happen.


I'm 99% certain that the Acela sets are semi-permanently coupled, which would make this event more noteworthy.
