SNCF are considering the possibility of creating 18-car TGV sets, according to the European View section in Modern Railways, October 2002, page 73, for greater passenger capacity. A double TGV Duplex set has a capacity of 1,092 seats whilst an 18-car set has a 1,124 seat capacity. The 18-car sets would be made up of two multiple 9-car sets using just two power cars, instead of the four power cars in a multiple double-set at present. To gain required tractive power, a power bogie would be added to each R1 car (an R1 is next to the leading power car and another next to trailing power car in a full 18-car set). This arrangement is used on a full Eurostar set to give the trainset twelve traction motors for driving power (see here how we made the Eurostar more prototypical some time ago). While SNCF thinks about their options, web•TrainSim decided to go ahead with an 18-car TGV Duplex set for the LGV Med. 29-Dec-02 update: the lounge car passenger view has been tried and tested in both the R1 and R1D powered cars. This solves the mysterious behaviour mentioned yesterday. Actually the mystery of the passenger view from the bar was explained once web•TrainSim had looked further than his nose and saw that cars R4 and R4D have a bar. See below under Passenger views to go about copying and pasting the passenger view code from the default R1 car. You can save time and energy by downloading the powered R1 and R1D ENGine files and the four consists. Here's the latest news (repeated from the line news of 28-Dec-02) on 28-Dec-02 in relation to the 9-car and 18-car Duplex trainsets: • <28-Dec-02>: The day started with the aim of doing a run from Valence to Marseille with an 18-car Duplex formation that we worked on yesterday. While musing over brekkie (no, not muesling), the thought came that the cars in a Duplex trainset are articlulated, i.e., cars R2, R4 and R5 share common bogies, whereas cars R1 and R8 have a full bogie set at one end and an articulated one at the other end. So we'd better have a look. Start up MSTS and choose the Valence-Marseille standard activity on LGV Med 2. What? Send a message? What's going on here? Whenever MSTS is this unhappy, one has to think back to what change or changes were last made. Well, the only changes to LGV Med were the 9-car and 18-car consists made yesterday. Start ConBuilder and test them. No problems. What else might be causing MSTS to hyper-ventilate? Brackets! In the comment line of each 9-car and 18-car consist file, web•TrainSim had put something like TGV Duplex 18-car (2x9-car, R1 powered). The brackets were removed and MSTS re-started. No further problems, until web•TrainSim thought he'd better do something about having two R1 cars in a 9-car consist. This situation just wasn't right since, when looking externally, bogies wouldn't be correctly placed. So remove the un-powered R1 car. No, MSTS didn't like that, so put it back in and all is ok. However, removing the un-powered R1 from the front did work for an 18-car consist, but, somehow or other, the passenger view changed to the view from the bar (in the second un-powered R1 car at the back of the trainset)! Ahh, MSTS. web•TrainSim is now off to take his 18-car Duplex from Valence to Marseille, as originally planned. When there's a spare moment, he'll be thinking about putting the passenger view into his R1 and R1 Deluxe powered cars (i.e., into their ENGine files). The download archive of these ENGine files and consists has been updated!
Here's what you do to put a power bogie onto the R1 passenger car. After web•TrainSim made a copy of the second power car's ENGine file, he referred to the R1 WAGon file for size dimensions, mass and friction. Mass is probably a little out on the R1-powered car since a bogie with two tractive motors and driving axles would weigh more than a non-driving bogie set. An important point to note is the name string for Wagon () (in two places) and Engine (). Obviously the WagonShape () has to be set to now refer to the R1 car's shape file. The R1 carriage in the default TGV Duplex installation is the first-class coach with a passenger view. So that's been left alone and now a 9-car set actually has two R1 coaches. Consequently swapping passenger views between the first-class car and the bar car doesn't get upset in any way using the batch files in TGV2N. Here are the steps to put a powered bogie under the R1 car:
Wagon ( TGV2NR1Mot .............. WagonShape ( TGV2NR1.s ) Size ( 2.91m 4.5m 21.845m ) CentreOfGravity ( 0.0m 1.5m 0.0m ) Mass ( 41.0t ) WheelRadius ( 0.45m ) InertiaTensor ( Box (2.91m 4.5m 21.35m) ) .............. .............. DerailRailForce ( "4m/(s^2)*41t" ) DerailBufferForce ( 200kN ) NumWheels ( 4 ) .............. comment( guessed brake force ) MaxBrakeForce ( 45kN ) .............. Friction ( 464N/m/s 0 1mph 0.977N/m/s 1.86 .............. .............. Engine ( TGV2NR1Mot Wagon ( TGV2NR1Mot ) Type ( Electric ) MaxPower ( 2200kW ) MaxForce ( 110kN ) MaxContinuousForce ( 100kN ) MaxVelocity ( 200mph ) MaxCurrent ( 1500A ) WheelRadius ( 0.45m ) Sanding ( 300mph ) NumWheels ( 6 ) RunUpTimeToMaxForce ( 4 ) .............. .............. Name ( "TGV Duplex R1Mot" ) .............. ..............
The following is a much quicker because we can use our TGV2NR1Mot.eng as a starting point and then we only need a couple of small changes, mainly to Wagon (twice), WagonShape and Engine, as you can see below. So:
Now use WordPad to make the following changes in TGV2NR1DMot.eng: Wagon ( TGV2NR1DMot .............. WagonShape ( TGV2NR1D.s ) .............. .............. .............. .............. Engine ( TGV2NR1DMot Wagon ( TGV2NR1DMot ) .............. .............. Name ( "TGV Duplex R1DMot" ) .............. ..............
Here's how you incorporate the lounge car passenger view into the R1 and R1 Deluxe powered cars. Once this is done, problems described above will be eliminated. Just remember to change your consists (see below). Start two copies of WordPad. In the first one, load the R1 WAGon file, TGV2NR1.wag, so we can copy the passenger view from this file to TGV2NR1Mot.eng which you can load into the second WordPad. Here are the lines in TGV2NR1.wag that we want to copy:
..............
Mass ( 41t )
InertiaTensor ( Box (2.91m 4.5m 21.35m) )
Inside (
PassengerCabinFile ( Premiere.s )
PassengerCabinHeadPos ( 1.01 1.655 -0.091 )
RotationLimit ( 50 270 0 )
StartDirection ( 0 0 0 )
Sound ( "Duplexpas.sms" )
)
Coupling (
..............
In TGV2NR1Mot.eng, scroll down until you see the following few lines:
..............
EmergencyResCapacity( 7 )
EmergencyResChargingRate( 15 )
BrakeCylinderPressureForMaxBrakeBrakeForce( 50 )
Sound ( "Duplexeng2.sms" ) Skip( defaut: TGV2NMoteng.sms )
)
Engine ( TGV2NR1Mot
..............
Learning from others' investigations with using a passenger view in ENGine files, i.e., giving a passenger view with sound in a loco, the Inside code should be the last code in the Wagon section of the ENGine file. That bracket two lines ahead of Engine ( TGV2NR1Mot denotes the closing bracket for the Wagon section. So now paste the lines you copied above in the position as shown:
..............
EmergencyResCapacity( 7 )
EmergencyResChargingRate( 15 )
BrakeCylinderPressureForMaxBrakeBrakeForce( 50 )
Inside (
PassengerCabinFile ( Premiere.s )
PassengerCabinHeadPos ( 1.01 1.655 -0.091 )
RotationLimit ( 50 270 0 )
StartDirection ( 0 0 0 )
Sound ( "Duplexpas.sms" )
)
Sound ( "Duplexeng2.sms" ) Skip( defaut: TGV2NMoteng.sms )
)
Engine ( TGV2NR1Mot
..............
Save this file. We're not going to copy this passenger view into the Deluxe R1-powered car, TGV2NR1DMot.eng, because the passenger view from the bar is in car R4D. Because MSTS uses the first passenger view it comes across, in our 18-car Deluxe trainset it will find the passenger view from the bar in car R4D. That means we've got some built-in variety. Of course, you could do things differently, that is the other way around: don't put the above passenger view into TGV2NR1Mot.eng but paste it into TGV2NR1DMot.eng instead. Another option is not to have the lounge passenger view at all; then you wouldn't have to do any of the above. If you do carry out the copy & paste job above, an easy way to remove the lounge car passenger view, without deleting the lines, is to Comment out the Inside code:
..............
Comment ( **
Inside (
PassengerCabinFile ( Premiere.s )
PassengerCabinHeadPos ( 1.01 1.655 -0.091 )
RotationLimit ( 50 270 0 )
StartDirection ( 0 0 0 )
Sound ( "Duplexpas.sms" )
) ** )
..............
Use ConBuilder or the Consist Editor to build four consists, naming each something like below (note that ConBuilder will tell you that you only have 8 wagons):
Note that until web•TrainSim includes the passenger view in the R1 and R1 Deluxe powered cars, the 9-car half-sets require that extra un-powered R1 car. For some reason MSTS gets very upset if that R1/R1D is not there!! |
