Slightly less inspiring is one of the demos done, where "token available" was shown for a short while on the opposing token machine after the token was removed. Mind you, it's almost certainly just an issue with displaying and releasing two tokens from the opposite directions wouldn't be possible.
Good evening, some single track museum railways in the United Kingdom are still operated with staff or token blocks although all their stations are equipped not only with home signals but also with departure signals (generally "railway semaphore signals" with arms positioned at 45º in the dial lower or in the upper quadrant to communicate to the driver that the way is clear). It is therefore not clear to me the need to have a staff or token block in the presence of starting signals. In other words, the signals that authorize the sending of trains in the opposite direction along the single track section could not be interconnected with each other in order to avoid head-on collisions as well as pile-ups as happens on double-track lines equipped with "Absolute block" ? If I remember correctly, the intermediate railway stations of the lines operated with the "Radio Electronic Token Block" do not have departure signals, except the "Stop Board". Grateful for the attention given to me, I would like to take this opportunity to extend cordial and sincere regards
Since RETB (Radio Electronic Token Block) has been operating on Network Rail and its predecessors since 1985, including in the North and West of Scotland for more than 30 years one wonders why someone got money to develop this extra system . I use the For North Line regularly and am protected by RETB. Why should other single line systems exist? Of course more technological systems need to be brought forward using GPS type software but the most forward example of single line working in the UK is RETB, 30+ years old as it is.
Mind you, at around about the same time the original RETB was developed, NSTR* was also introduced - -this video and the design of the token machine seems to suggest- a talk about DiBloc explicitly states that it's for those types of lines? RETB requires you to have the cab display radio/unit on each train, as well as the radio system itself (which could end up being in addition to the standard GSM-R**), and is more expensive than NSTR. This takes the NSTR/NSKT costs down more as there are more options to connect them together... (*No Signalman Token Remote - the first commissioning I believe was in 1986. Alongside the six lines that use it, there are also the other No Signalman Key Token lines. **The current RETB lines don't have GSM-R, seen it mentioned that the terrain on those lines isn't great for a reliable signal. The rest of the network though has had it fitted, and I don't see that anyone would happily make a case for removing it again.) Edit: these guys are the same ones who do the new generation RETB equipment, for what it's worth...

I'm sure it's in demo mode, but removing a token and having the token available light still lit in your promotional video isn't confidence inspiring!
