I'd suggest renaming "Telephone" as "Block Signaling"
Good idea, I also changed introduction date of wire line to 1833.
I used opengfx left-side semaphores and repaint them to looks similar to the optical telegraph towers (rather Prussian one than Chapel or Tolkien).
It looks good with catenary visibility switched off:

Every carrier have also option for viewport invisibility (it is always visible in depot/vehicle list, in such case invisibility is marked by darker colour).
I'd like to see service start earlier in 1840 with "Telegram" set at 1 mail bag, "Printed Telegraph" in 1875 set at 2 mail bags, "Teleprinter" in 1900 with 4 mail bags, "Telex" in 1930 with 5 bags, "ARPANet" in 1965 with 10 bags, and "Internet" in 1990 with 100 bags. I propose this because it gives a fairly even distribution of speed and technology that parallels history.
I don't want to provide such linear improvement of technology, because I don't want to make this newgrf (at least not at the early stage of the game) a kind of 'money printer' or concurrent to classic trains.
Arpanet was experimental system and was not known worldwide, first internet networks in early 90 were incredibly slow.
To the end of XX century, mail vans were used widely, the main reason of their withdrawal was rather better logistic provided by road vehicles, however sending emails, SMS or digital photos instead of postcards were also important factor, which I want to mimic within this newgrfs.
Thanks to George permission, whole newgrfs is now under GPL 2.0 licence and is available via content online.
Version 3.0 contain bloc signalling 'logic train' and four commercial carriers: telegraph, telex, 10BaseT and 100BaseT Ethernet.
Telex can carry now 2 mail units, Telegraph 1 unit and is twice cheaper than telex.
[/quote]I'm guessing you created this in NML and thus no stations are yet possible. some of the waypoints look sorta nice with it, though.[/quote]
Yes, unfortunately, I cannot provide neither stations or bridges (train wooden bridge with only pillars visible would looks good both for trains and telegraph line), but some ISR stations (for example low goods station) looks well.
It would be nice to see this simple NewGRF with 2x zoom sprites. The wires are definitely too thick in zoomed modes.
Good idea, I would also make these wires darker. Pity, that there is no option for partial transparency, like in case of stations.
I miss also company colours - without fences it is impossible to show track owner.
