    Hello everyone, I would like to propose to you the Line 8 of Métro Parisian exploited by ratp group.
    Line 8 of the Paris metro is one of the sixteen lines of the Paris metropolitan network. It connects the Balard stations, in the south-west, to Pointe du Lac, in the south-east, following a parabolic route by the right bank of the capital partly common with line 9. (the metro is supplied with 750 V DC on the 3rd rail).
    It is the only Parisian line to cross a river and its main tributary: the Seine, underground between Concorde and Invalides, then the Marne, by aerial between Charenton - Schools and Maisons-Alfort Veterinary School. It is the first line tied with line 7 in terms of number of stations (38), although it does not have any branches; it is also the line whose terminuses are the furthest away by the route (23.36 km). The back station of the Balard station is located under the grounds of the Paris heliport, beyond the viaduct of the Boulevard Périphérique. This station is made up of three quayside tracks including a central which plays a dual role of arrivals and departures. The end of the line is completed by four sidings (A, B, C and D). Up to the terminus, the line has three tracks. Before arriving at Créteil - L'Échat, it crosses the RN19 / A86 interchange and then goes out into the open for good. The route is between the tracks of the departmental road 1 (RD 1) and serves the stations Créteil - University and Créteil - Préfecture . The line continues due south to arrive at the crossroads of RD 1 and RD 60 then at the Pointe du Lac terminus. The line continues to arrive behind the Dominique-Duvauchelle stadium in Créteil where the new maintenance workshop is located.

    As of October 8, 2011, the complete route of the line required 52 minutes in each direction, which constitutes the longest journey time between the Paris metro terminus, on par with line 9. As on all the main metro lines, the first departure from a place at the head end at 5.30 a.m., but the length of the line causes a first partial circulation in order to ensure service at the same times as the other lines without exceeding too much the hourly amplitude of service . Thus, a first departure takes place at 5:21 am from La Motte-Picquet - Grenelle to Pointe du Lac and at 5:34 am from Daumesnil to Balard. The train that left Balard at 5:30 am did not reach République until 5:50 am. The last departure to Pointe du Lac was at 12:24 am from Balard. The last departure to Balard is at 12:24 a.m. from Pointe du Lac. The last departure for a complete route is set at 1 h 24 in both directions on the nights of Fridays to Saturdays, Saturdays to Sundays and from public holidays to public holidays.

    Rolling stock:

    The rolling stock to be used is the MF77 (Metro on Fer 1977). it is designed to operate long extensions in the suburbs, with a more comfortable layout and a top speed of 100 km / h, which is however not exploited thereafter. line 8 currently has 58 trains out of 197. The 197 trainsets are delivered in a 5-car configuration (M + B + NA + B + M). The motor coaches with driving box, designated M, weigh 29.5 tonnes; the trailers, designated B, weigh 21.4 tonnes and the motor cars without housing, named NA, weigh 29 tonnes empty.

    It's 14.5 miles - .1 of a mile longer than the Bakerloo Line. And, with a similar mix (seemingly) of above and below ground, the experience won't be all too different, unless the rolling stock is drastically different.

    So, mooredean1978 is correct that it is a short route. However, I do have no objection to more French content, and I'd be more than happy to see it.

    But it is a bit on the short side.

    Thank you very much for this positive feedback. Yes in terms of traction rail it is similar to the London Underground but there is only the 3rd rail

    I don´t think that this line has any station outside its entire route, which would make it very boring.
    I'm sorry, but I would consider lines 2 and 6 better options (including both, since they run through all of Paris and connect at their end stations):

    upload_2021-11-30_21-59-39.png

    Half of the route on both lines is outside and it would not be so boring.
    We already discussed this in the old thread:

    If line 8 goes to 4 stations and an inter-station between Charenton school and Alfort house veterinary school on the Charenton bridge. but I agree that lines 2 and 6 would be interesting :)

    Security system:

    The Paris metro is equipped with safety systems such as VACMA on the pedal and on the manipulator standby. If one of these procedures is not applied, the train causes an automatic stop in emergency braking and an alarm signal sounds just before the train stops unexpectedly, you have a bell that sounds to warn you that you are pressing not on the VACMA. You also have an alarm which sounds if after closing the doors in the station after 3 seconds you do not start the train and to stop it there is the BP NA (alarm deactivation pushbutton). In inter-station you also have this alarm which sounds when you are stationary without having opened the doors and at each stop where you do not open the doors. You must press the BP NA immediately.
    You also have the KPV (Spot Speed Control) which checks if you do not exceed the prescribed speed in tunnels and outdoors in inter-stations. If you speed excessively above 5 km / h you trigger the automatic train stop, obviously with the following emergency braking on the part of the driver.



    Rail signaling Part 1:
    Now let's talk about the subway rail signaling. DTG Natster

    Spacing signage:
    Each line is divided into relatively short sections, called cantons, protected by lights which, in normal driving, should not be crossed when they are red. A repeat signal is used in the event that visibility does not allow the driver to react in time (yellow if the next light is red). In the normal case, there are always at least two red lights between two consecutive trains (i.e. there is always a free block between two trains). However, to increase the flow of the line, a train is authorized to enter the station by a yellow light E, as soon as the preceding train has released a few tens of meters downstream from the platform and not the entire following block; this change to yellow is accompanied by a speed limit indicated on a light panel next to the signal.

    There are also station output signals, and so-called spacing intermediate signals marked with an I, to which an index is added to differentiate them when there are at least two. Signals are numbered 1 to 1, in ascending order to the next station. We can therefore find in an interstation either a signal I, or a signal I1, I2, etc. Separation signs are circular in shape and arranged vertically, with a green light indicating the lane free, yellow for the warning and red for stopping. Some interstations do not have I signals, but just an output and input signal.

    There are also so-called “early release” signals. This type of signal generally has two lights and has the advantage of presenting a green light when the preceding train has cleared a point in the station. Typically, it is placed shortly after a "leading signal" which behaves similarly to a single spacing signal repeater. The mark of this signal has a luminous point.

    Finally, we can find spacing signals identified only by a number, nicknamed "overlap". These are fitted to the tracks used to perform the main track change maneuver in certain terminals and are systematically preceded by a repeater.

    220px-Metro_Paris_-_Ligne_1_-_FQ_signal.jpg images (7).jpeg


    Maneuver signaling:
    The maneuver signaling is located at the switches. We can therefore find it:

    at the terminals, near the sidings and reversing tracks;
    in line, near connections between lines;
    in line, near certain track devices (switches) intended for provisional services.
    The maneuver signals are marked with a letter, which may be followed by an index and / or a star (symbol "*"), and two or three rectangular lights arranged horizontally:

    the red light orders the train to stop completely. When the maneuver signal is equipped with a traffic authorization button (these signals are identified by the star on their plate), pressing this button turns on this flashing red signal. In this case, crossing by sight is authorized in order to reach the parking position;
    the yellow light, then associated with a speed indicator panel (TIV), authorizes the passage at a speed lower than the speed indicated by the TIV until the next maneuver signal, the next TIV or the stopping point (in l (absence of TIV, the speed is 10 km / h);
    the green light allows passage.
    The shunting signals are controlled by the local shunting stations (PML), which manage the parking positions.
    In line, in the event that they also function as separation signals, they are controlled by train traffic. The signals protecting switches and crossings are ordered:

    either on the job (by operating the lever controlling the needle, or by a remote control generally located in the station);
    either by the PCC of the line, remotely. In the case of inter-line connections, internal documents specify the role of the PCCs on each line, there is no general case.
    In all cases, they are systematically preceded by a repeater signal with two or three indications: a green light for a green maneuver signal, a yellow for a red maneuver signal, and two yellow for a yellow maneuver signal.

    But in the case where the repeater signal also acts as a separation signal, it can then present three or four indications: green, red, yellow, or two yellow if the signal concerned precedes a maneuver signal with three lights.

    360px-Metro_Paris_-_Ligne_3_-_station_Pont_de_Levallois_-_Becon_-_Signal_manoeuvre.jpg Metro_de_Paris_-_Ligne_3_-_Opera_-_Signal_01.jpg

    In addition to the separation and maneuver signals, the driver has a number of additional indicators.
    Tunnels and viaducts sometimes create areas where visibility is reduced. In a tunnel, these zones are indicated with the help of markings painted on its piers, comprising:

    black and white bands indicating the start of the reduced visibility zone;
    black and white mirlitons then distributed at regular intervals along the area of reduced visibility;
    black and white bands indicating the end of the reduced visibility zone.
    On the viaduct parts, these markings are installed on the lateral metal structures of the deck supporting the track.

    Rail signaling Part 2:

    Speedometer panel (TIV):

    Speedometer boards consist of white numbers on a black background. They are used to indicate the maximum authorized speed. They can be found on track or associated with a maneuver signal if they precede a switch.
    70px-Métro_de_Paris_-_Indicateur_TIV.png

    Traction current supply indicator:

    The traction current supply indicator consists of small white illuminated squares on a black background, generally forming a "+". The vertical bar, which forms a cross, represents the supply of traction current to the tracks. In the event that the traction current is cut (following an electrical incident, for example), the indicator then displays a "-" allowing the driver to indicate the absence of traction current.
    70px-Métro_de_Paris_-_Courant_Traction.gif

    Departure on order (DSO):

    Departure on order is an indicator made up of three small white lights arranged in a triangle. Its ignition makes it possible to retain the trains in station. When it is on, the three lights that make up the signal flash simultaneously. Its extinction authorizes the departure of the train (if no other signal comes to contradict this order). Generally, the extinction of this signal is accompanied by a prolonged audible signal intended for the driver. The departure on order is likely to be used for regulation purposes by the line regulator by slowing down a train (prolonged parking in a station) or by accelerating a train (shortened parking in the station). It can also be the result of the de-energization of part or all of the line, or of the ordering of a signposted temporary service.
    140px-Métro_de_Paris_-_Indicateur_DSO.svg.png


    Provisional service (SP):

    The SP indicator consists of the inscription "SP" in a luminous block on a black or blue background. This indicator, when flashing, warns the driver of the establishment of a provisional service at this station, that is to say of a provisional terminus requiring a change of direction of the train.

    This indication is supplemented by two indicators: "DEPARTURE" and "QUAI 1" or "QUAI 2", with fixed lighting, when the change of tracks is made upstream of the platform where the train arrives. The "DEPART" indicator specifies that the train must leave online directly from this platform, while the "QUAY" indicator specifies that the train must go to the platform of the opposite track. These indications are only present for provisional signposted services: in communications with simplified or even non-signposted equipment, only an “SP” indication on a slate placed at the head of the platform indicates the setting up of a provisional service.

    Provisional service is the consequence of a traffic disruption which may be unforeseen (incident, safety measures, material damage) or foreseen (works). In order not to stop the traffic on the whole line, the regulation sets up provisional services on the portions of line which can be operated in complete safety and which have the necessary switches and crossings for the overturning of the trains
    .

    Rail signaling Part 3:

    Direction indicators:
    The direction indicator informs the driver of the direction given to his train if the indications of the maneuver signals are insufficient.

    It can take, depending on the case, two forms:

    attached to a signal, it is in the form of a square of diodes displaying the marker of the track towards which the train is headed (for example T for the sidewalk) or 0 if the train is performing a 0 maneuver (turning over to the platform
    );

    Regulating pendulum:

    At the head of some docks is sometimes a case with four pendulums, lettered A, B, C and D, as shown in the illustration at the beginning of this article. These clocks allow the driver to know if he is early, on time or late. Each letter corresponds to a period of service; when a train arrives at the quay, only the period clock remains on.

    Letter of Service Period
    A: evening rush
    B: Morning rush
    C: Off-peak hours during the day
    D: Off-peak hours in the evening

    When leaving his original terminal, the driver sees his train set with a departure time (in hours, minutes and seconds, for example 10:05:00). When he arrives at a station on the route equipped with this box, only one of the clocks remains on and indicates the time (in minutes and seconds) at which he should have left the original terminal if he had driven at normal speed. If the clock shows an earlier time (for example 04:30), this means that the driver has left in advance, here by 30 seconds (at 10:04:30), and vice versa if the clock shows a later time
