How RAILWAY SIGNALLING Evolved from Flags to 4G Network

can have a detail video about CBTC

Love this video - Now Subscribed to the channel... 👍🚦🚦

The "flashing green" was introduced at the SNCF: trains traveling at no more than 160 km/h could consider it the same as any "steady green"; instead the driver of a train traveling at more than 160 km/h had to slow down until the speed was reduced to no more than 160 km/h before passing the next panel. A pre-announcement signal (P) was also provided for mobile TIVs when presented. A similar pre-announcement signal was also foreseen for what concerns the TIVs of the construction sites (temporary signs placed to order the reduction of speed in correspondence with sections of line along which works are being carried out). Instead here in Italy, to allow circulation at speeds above 160 km/h along the "Direttissima" Rome - Florence, they invented the repetition of signals (Cab signals) with 9 codes, adding a second carrier to the one used for the "Automatic block with coded currents" of the American school.

Time Interval System. Until around the 1920s, here in Italy and in other European countries (France, Switzerland, etc.) the green flag or light meant slowdown, danger, etc. and the yellow flag or light did not exist. I would therefore kindly like to know whether the green, then yellow and finally red flag sequence seen at the beginning of the animation which deals with the "Time Interval System" is historically reliable or not. Thank you very much for your availability and collaboration

Sir, can we get presentation for this session..

Superb video..request link for video on using 4g technology

What are electromechanical signalling systems?

Do they use 5G now?

Holy shit
I understand all train signal systems in games now


That's.. brilliantly simple.
How collide... if they aren't at the same location.
Just dont enter the same block
Brilliant

Why not the same be followed in Road transport thereby
1.Rash driving
2.Drunken driving
3.juvenile driving

Can be avoided.

Yet another video done brilliantly to explain so even an amateur can understand. Brilliant. Thank you. Greetings from Sweden 🇸🇪.

How does railway coding work

How much time passes between a green signal and the train arriving . in the UK
Thanks !

Thank you for sharing, i wouldo like to nkow more about signalling and Railways Communications systems based on GSM-R ou LTE-R Tech

Interesting video!
Would be nice if you would do more videos specifically on signalling topics

We still use flags in our country

Thanks for giving knowledge of railways signals sir , The fear of the lord is the beginning of knowledge but fools Despise wisdom and instructions sir, all the best regards sajjan kumar chotia son of yeshua god Jerusalem Israel

Thanks for giving knowledge of railways signals system , Every where a man is respected on account of his quality sir all the best regards sajjan kumar chotia son of God

Yes I am interested ☺️

i just got hooked with trains and then i found your channel and its amazing! keep up the good work!

Can you make video about electrification standards?

Block System seems rather crude.

Terrorists must not know about Track Ciruits.

Very well explained. Great presentation. Thank you 🙏🏼

In continental Europe the mechanical signals are whole different

Good job

Good information and great graphics, but the monotonous, robot-like voice is hard to endue after a few minutes.

True informative video 👍 please make video on KAWACH automatic safty system developed by Indian Railways 😇

Very boring and monotonous tone!

Aye!
Loving that video at the end of AMTRAK crossing the Schuylkill River in our home city of Philadelphia.

💪🏾💪🏾

left out cab signalling

Great video. I always stared at the signals at signals, and wondered how they worked.

Interesting

Yes, interested:)

Actually, although 160kph (100mph) is a common limit for lineside signals, some countries, in particular the UK and France, allow running up to 200kph (125mph) under lineside signals. The UK also did do test running at 225kph (140mph) using an extra flashing green aspect, but this was never used in service (although the flashing greens are still present on the route where the tests took place).
The main variation from the basic green-yellow-red system is speed based signalling. These tend to still follow broadly the same principal, but add in additional aspects (either multiple aspects together, flashing aspects or both) and sometimes will even display maximum speeds. Some systems will also have different forms of red signal, one being an absolute stop, and one being a "stop and proceed with caution". The UK has it's own variation on green-yellow-red which adds in an extra "double yellow" as an advanced warning, allowing trains to run closer together by reducing the block length whilst still maintaining the same braking distance.

So wonderful is the progress of technology. Only in US we will continue to have fatal crashes, because the weakest link is the human fools. You can make thing safer by foolproofing the design, but nature always make better fools.

I HAVE BEEN FOR YOUR TIME WITH TRAVELING TO I AM A CLASSIC CAR FOR EARTH. STATION WAY 🚰🚻🚾♿🚹🚺

Thanks for all the info. I would be interested what fall-back systems are in place, if there are power outages, the 4G network is unavailable, or any bigger computer sabotage happens. If there is no signaling installed on the line, does that mean that all freight and passenger transportation can be brought to a standstill on all those major transportation lines, just by knocking out those critical networks?

Here in the UK, the semaphore (mechanical) distant signal was a separate signal coloured yellow with a triangular notch cut out at the end to differentiate it from the normal signal

It was an excellent video - I'm not sure the timed version of the signal was in place here in the UK but I could be wrong

Thank you for giving Imperial measurements along with metrics it makes it so much easier

You neglected to mention the position light signals used on the former Pennsylvania Railroad system.

Thanks for this informative video on railway signalling, From childhood i have been fascinated by the Railways and still that enthusiasm of train journey has not receded, i always take a train for a overnight journey, during my young age i used to see only Semaphore signalling and that too some had oil lamps at night, put up by the gangmen every evening and slowly this changed to lights with the cables from the signal switching post run to a distance with rollers The mechanical hand lowered or lifted up to show proceed was a marvellous and slowly colour light signalling takes over, i was waiting to hear you say about the keys transferred from one station to other y the loco pilot and this helps to operate the signal lever so that the loco pilot understands whether the block is clear or not clear. There used to be a bamboo bent like a tennis racquet and a leather wallet belted to this will hold the key, when passing a station the loco pilot drops his and grabs the one held by the gang men, this was lovely to watch especially during night when he holds the key with one hand and fire torch in the other, Please show more videos about signalling.

Good information
