Power Cable (PC):
1. As stated elsewhere in this text, the power rail that carries the electric power for the trains is not on all the time, instead it is split into sections and each one switch on only when a train is on it.
2. In order to get the electric power to the power rail and to other places to the left and right of the track, a 3 phase power line is suggested.
3. BUS BAR: A low price, but effective solution would be to use 3 bus bars that are mounted underneath the power rail.
4. The bars can be round or rectangular.
5. Each of the 3 bus bars are inserted into a separate steel tube that is insulated on the inside, whereby the bars can also be insulated.
6. The tubes can then be filled with an epoxy raisin, in order to ensure that it remains waterproof, even after a fracture.
7. Each section of a bus bar is mounted underneath the power rail and joined together with the next section inside a junction box at each connecting point.
8. The power rail and it's posts are strong enough to carry the weight of the 3 bus bars.
9. A fourth steel tube will be required for telecommunication lines.
10. In order to keep things cheap for the railway, their low frequency communication signals can be inserted directly onto the bus bars and extracted at the required points.
11. In fact, by using cheap repeaters connected to each of the three bus bars at distances between 300m...1km apart, with each bus bar carrying between 1..3gbit/s of data, the amount of data band width that would be available for sale could be between 3...9gbit/s for each side of a train track, with a SHE for each side and the data carrying capability is planned in from day one.
12. It would be quite a large amount of data, if railway lines that cross African international borders were equipped to carry that amount of data.
13. It would be an internet that no one has ever heard of before and everyone in Africa would be able to reach everyone else, no matter which direction the signal routing path takes.
Don't be discouraged
