| | | My 0-4-0T Porter can easily pull about 3 times the load that my 4-8-4 Greenbrier can. WHY!?!?! Does anyone have a suggestion about why the little one pulls so well? The 4-8-4 has about the weight of the Porter at the rear over the motor, and runs (...) (22 years ago, 25-Oct-02, to lugnet.trains, lugnet.org.us.michlug)

| | | | In all fairness. the LEGO® train motor does not have that much inherent tractive effort to begin with...hence the addition of rubber traction tires on the wheels. The train motor was designed to pull only their assigned train cars within a set (i.e. (...) (22 years ago, 25-Oct-02, to lugnet.trains)

| | | | (...) That only adds to my confusion. The Porter has the old motor and my Greenbrier has the brand new (3 days old) motor. I did take out a battery box which really wasn't needed, and it's a bit better, but I can't make the engine much lighter. (...) (22 years ago, 25-Oct-02, to lugnet.trains)

| | | | | (...) Okay, then your problem is drag. Weight isn't so much a problem if there isn't a lot of friction. I just looked at your engine again and I can see your problem, because it is one that my son Ross experienced when he built his Pacific: (URL) (...) (22 years ago, 25-Oct-02, to lugnet.trains)

I did disconnect the two center drivers from the side rods, which reduced strain on the 9V motor, (...) (22 years ago, 25-Oct-02, to lugnet.trains)

You're running a separate motor to drive those wheels, and I know from you in person today it's running on the output studs from the train motor. That's taking power away from the (...)

| | | | | | (...) Hmm... I see what you mean about drawing current off the motor, Peter. I ought to double motor the thing, but that would mean losing the 3-axle trucks, which I want to avoid. Ross, does your stuff run off one or both motors? I'm putting the (...) (22 years ago, 28-Oct-02, to lugnet.trains)
