| | | All, Back to the wonderful world of trains. Here are the pictures of my latest creation, a Southern Pacific 4449 Daylight engine with a compliment of coaches. The engine, a 4-8-4, has connecting rods between the drive wheels that really move with (...) (25 years ago, 6-Nov-99, to lugnet.trains)

| | | | | I'm not a big fan of steam but this looks very sweet. One question I have about the drive train, the distance between the front and back pivot points needs to be shorter when going around a curve than when you're on a tangent. How do you accomodate (...) (25 years ago, 7-Nov-99, to lugnet.trains)

There is a sliding joint between the forward pivot in front of the drive wheels that translates forward and back relative to the leading truck. Thus, when the train goes around curves, the joint (...) (25 years ago, 7-Nov-99, to lugnet.trains)

| | | | | | (...) You talk about the trucks sliding forward and backwards. It seems to me that the body would hinder this from happening due to the fact that it connects to the the front and rear trucks via two stationary pins. Since the body doesn't stretch (...)

The drive wheels simply move away(towards the back) from the front truck around the curves. There are no springs used (...) (25 years ago, 7-Nov-99, to lugnet.trains)

| | | | | (...) To start, great train! I love late steam locomotives but, have been frustrated trying to come up with a drive mechanism that is both reliable and prototypical in appearance. My current design uses two drive moters in an articulated set-up with (...) (25 years ago, 8-Nov-99, to lugnet.trains)

| | | | Hi Ben, It just occured to me that you train should be able to use switching points, right? Those wheel rest on top of the rails, so they do not stick down in between the rails, right? By the way, I tried a bunch of the links on your train site and (...) (25 years ago, 17-Nov-99, to lugnet.trains)

| | | | Chris, It moves through points with no problem. The leading and trailing truck which have flanged wheels make sure of that. The middle drive wheels are pretty much just along for the ride. My train site seems a bit hosed and I believe it may not be (...) (25 years ago, 17-Nov-99, to lugnet.trains)
