TRAMWAY with 6 different trains

In 1960, almost all the trams had disappeared, and from 1980 the trams reappeared in the big cities, more modern, but with the same principles as the preceding ones.

Here is a 20% faster tram ...

This new tram replaces an existing tram: With identical cars and as many cars, but twice as many cars per train and twice as many trains.
A set of 6 trainsets of a car which follow each other closely replaces 2 current tram trains, this makes it possible to transport many more travelers without increasing the length of the platforms of the stations, because the commercial speed is 20% higher.
The crossing with the road traffic is done in 1min 30 because the interval between the 6 cars of the set is very close.
In addition, it is possible to cross some cars on the road when 2 cars of the set are stopped to pick up travelers, (see diagram below).

Each tram only stops at 2 out of 4 stations.
1) The commercial speed is then 1.3 times faster, avoiding many stops.
2) The passenger flow is then increased by 30%, because the average speed is 30% faster and the interval between sets is reduced.

3) In off-peak hours, the frequency of trams is identical to peak hours, because the set of 6 cars regroups and stops in all the stations but a few cars remain at the terminus to reduce the number of cars in circulation.
4) In a station that is overcrowded at certain times (shows, sports matches, etc.), all the trams will then stop, ie twice as many trams stopped than usual. Travelers coming from another station can take any tram to get there, so 3 times as many trams as possible from another station
5) No additional cost of civil engineering, no additional cost for cars which are identical to existing tram cars, only the data processing and the position of the landing doors are changed.
6) The frequency between the sets of 6 trams is identical to the frequency of the tram currently, but the speed of the 6 trams being 30% faster, the frequency between the sets of tram is therefore 1.3 times faster than the frequency of the tram currently. This increase in frequency adds to the time saved by travelers by avoiding half of the tram stops.

Example of a station for travelers

The traveler looks at the color of his destination, to choose the train with that color.

The traveler takes the first or the second set that stops:

Blue-red or blue-green which stop one behind the other.


Blue-Yellow which stops by itself.

To go to a blue station, the traveler can take any train that stops

In off-peak hours

In off-peak hours, the tram becomes classic again, but rather than reducing the frequency, we reduce the number of cars in the whole (at the terminus).

Thus travelers always have a high frequency of trams.

Crossroads with road traffic.

Example between station B and station C: the zone in yellow shows the possibilities of crossing with traffic.

Comparison between current TRAMS and trams with 2 stops at 4 stations.

In 9 minutes:

Currently, 3 trams run in 9 minutes.

With the new tram, in 9 minutes, 6 smaller trams run faster with 2 stops at 4 stations.

The commercial speed of trams is currently slowed down by stops in stations and incidents when crossing with cars and passers-by:

Additional cameras can be installed at intersections with road traffic and broadcast images in the tram cockpit to assist tram drivers.
