I've noticed that many of the pictures and rides

posted use a four car train configuration. I plan on getting a couple more sets, and was

curious if any of you have found advantages to a four car train over the original three.

Does five or more cars cause complications (lift problems most likely or foreseeable),

or more speed. Just curious.

The more carts on the track the slower they will go

[live4bb21]

more cars strain the motor, it has more speed but it

loses the speed easier.

With the original knex coaster, I used tires to weigh

the car down, creating more speed, but mainly to keep it on the track (not locked like

the SS). Anyone tried adding weights to the train? And, for those that have added

pieces to the cars (for inverted, flying, X, or steel coaster train look), does that make a

significant difference in the motion of the train? Thanks for the tips.

Adding more cars does

not make it go slower, only faster. The more momentum it has, more weight and more

momentum are two totally different things. The cars do not make it slower because it

is adding weight, the weight is flatened and spread out, as each car goes around a

cuve, different supports will be supporting a single car as it goes by, it's not like

all it's weight is put in one 3 inche lenght. Also if you make the pullouts large

than it can greatly help because the front of the train is going over the hill and pulling

more speed to it, if you have small hills and pullouts then it would probably take away

a small big,.....a small bit.
Also it's not that difficult to make a lift work with

a 5 car train even with one motor and with ease, I think I might make a tutorial to

show how I accomplish this.

the more cars used on a model means more wieght but

also more strain on the motor i think weight on the carriage aint the key for it to go it

uses less wei9ght and he more i will fly round the track

If you make an outstandingy strong support structure

the larger amout of cars will help you. The KE (kinetic energy) it will have is

determined by speed and mass. So the larger train has a better chance of making

through the course with a stronger support structure.

Well put Riordan! you simplified

my post, lol, j/j.

I allways use three cars because thats all I have. Even

though I have two sets some of the cars connecters got busted.

[CostaKid]

Well, the more cars you have, the faster it will go, but...

you lose your speed quicker because there is more friction created by the extra car.

[Shockwaver]

The more cars on a train will make the weight on the

supports at a higher level. Knowing k'nex, the track bends a lot Also, the faster

they go over a hill, the up-stop wheels arent moving so if the train is going too fast

over a bunny hop or sompm like that, the train will jump and force the up-stops to

move, which makes the train slower.
