Just getting started

Just getting started in model railroading....now really sure where or how to start.... Is it better to use code 83 or code 100? Also is there a difference in 6 axle and 4 axle locomotives besides size and appearance?

Code 100 has been the standard in HO for many years, but it scales taller than the rail used on the prototype. Virtually anything in HO scale can operate on it. Code 83 is within the size range of real rail and so looks more realistic. Older model railroad cars and locomotives usually have deep wheel flanges which may be too deep to run on Code 83 (rolling on the ties instead of the rail). Wheels on cars are generally easy to change, but loco are more problematic.------------ Starting out today, I would go with Code 83. Unless you buy some older used locomotives with deep flanges you should have no problem since today the locos and cars have flanges compatible with Code 83.---------------------------------------------------------------------------------- Generally model 4-axel locomotives can operate on slightly tighter curves than model 6-axel locomotives. --------------------------------------------------------------------------------------------------------- On the prototype 4-axel and 6-axel freight locos were used for different type of service although there was a lot of overlap. 6-axel freight locos came to predominate in the mountains where they could lug heavy loads up the hills. 4-axel on the flatlands. ------ The first diesel freight locos were 4-axel. for example using EMD locos: FT through F9 "covered wagons". They were supplanted by the GP7-GP9 "hood units" which were mechanically the same as the F's. The GP series development continued after the F series stopped: GP18, GP20, GP35, GP40 and up. The SD series with 6-axels are basically lengthened GP's. ------- Today Class 1 railroad main line locos are virtually all 6-axel. Short lines often still use 4-axel locos (often refurbished GP's)

I have found that if you are going to use 6 axle engines you need to be sure your track is level without dips and bumps. 6 axle engines will derail more easy than 4 axle engines. Hope that helps you

Thanks for advice.... I'm sure you all be hearing from me again for advice... Excited to get starting in great memories with kids not to mention all the Fun....
