Given that the original trains were unmanned, what would be the point of wayside signalling? There were some manned, battery-powered trains, however. If there was a curve in the line that would obscure the line of sight and another train were stopped beyond the curve? I'm assuming the battery locos only ran when the automatic trains were not running (ie, when track power was off). Also worth noting that the trains could obtain speeds upwards of 35 miles. The trains were stopped and started by turning the power off and on on the section of track they were travelling on. Did power supply from the track feed into a relay for the trains' brakes? Not quite. Quote: The trains brakes are held off by electromagnets whilst its receiving power and on the move, but when it hits a dead section of track the train brakes are automatically applied and held on by large springs. When the Railway was first opened, it was controlled from control panels located in the inter-platform tunnels at the stations. These panels allowed trains to be shunted in the station, or routed straight on to the next station. The switch panels were mechanically and electrically interlocked. Outside each station is a short dead section which brings each train to a halt. If they can be admitted, the line controller could operate a receiving lever controlling a camshaft motor which closes three relays progressively bringing into use three different voltages to control the trains rate of approach. The first relay energizes the dead section at normal line voltage, 440 volts and sets the train going, the second relay reduces the voltage to 206 volts, so slowing up the train without the use of brakes (remember the 1 in 20 gradient) and the third relay reduces the voltage to 150 volts which brings the train into the station at 8 miles an hour. On entering the station, the train rides into a dead section and the brakes are automatically applied. 1993 saw the installation of a £750,000 computer to take over control of the system from one central point. The Vaughan computer directly interfaced with the existing control system. The computer system was bought into operation section by section, this allowed the system to carry on operating as normal during the installation. Each station had its own computer, interfaced to the existing relay system. The computer could control the progress of each train on the system automatically, if needed the line controller could take control of any part of the system, and reroute trains as needed. http://www.mailrail.co.uk/operation.html What would happen if another, unmanned train were on the track ahead? The battery loco presumably wouldn't have been running on track sections occupied by service trains. Will the tentative journeys on offer run from Whitechapel all the way out to Paddington via Mt. Pleasant, BTW? No, nothing like that. It's just a short demo loop. |

Again, possibly too remote from the supply end for power cables. For comms, maybe only usable if the two ends are conveniently close to the existing stations but fibre-optic cables only need a reserved space on the cable bearers rather than the entire tunnel as would necessarily be the case with HV cables.

Given the traffic situation in London there must be some business case for it. The sorting offices have long been dispersed away from Central London and well away from the PO railway. I'm pretty sure, if memory serves me rightly, that the thing that ended the viability of the PO railway was the opening of the major postal distribution hub at Willesden. Some people did suggest extending the POR there, but that was pretty much a non-starter - can you imagine the cost? No imagination this country , what would be wrong with a bit of mixed gauge out of Euston. Since rail ferries carry trains on boats, and Le Shuttle carries cars on trains, why not have a train-train which carries the PO railway wagons on mainline gauge flat wagons with narrow gauge rails laid on top of them? There should be enough paths on the DC lines for them. The only problem (yes, I did say *only* problem) would be that the mainline railway runs in the day and is maintained at night whereas the PO railway ran at night and was maintained in the morning IIRC. |

Given that the original trains were unmanned, what would be the point of wayside signalling? There were some manned, battery-powered trains, however. Where 'some' = 'one', IIRC. If there was a curve in the line that would obscure the line of sight and another train were stopped beyond the curve? Presumably the manually driven trains were only allowed out when control measures were in place to stop automatic trains from running. Also worth noting that the trains could obtain speeds upwards of 35 miles. The trains were stopped and started by turning the power off and on on the section of track they were travelling on. Did power supply from the track feed into a relay for the trains' brakes? Yes. AIUI there were three voltages that could be applied, for full speed, medium and low speed. Zero voltage applied the brakes. What would happen if another, unmanned train were on the track ahead? I don't know but I'd imagine some measure was in place to prevent collisions. Perhaps the presence of a train in one section rendered the previous section dead? Will the tentative journeys on offer run from Whitechapel all the way out to Paddington via Mt. Pleasant, BTW? No, AIUI it's just from the depot to Mount Pleasant station and back. Anna Noyd-Dryver |
