I have a Klein Modelbaun locomotive with working pantographs and two matching passenger cars. 1.) Which brand of track would you recommend to use? (Currently only have two pieces of Walthers bridge track code 83 with code 70 guard rails and the pieces seem to roll fine on it.) (I dont have any other track or track guages right now to test with.) 2. Are there any manufacturers of flex track in code 83 with code 70 guard rail (either single or double) that is NOT bridge track spacing on the ties ? (In other words, normal tie spacing) I'm wanting to use guard rail on my curves on the layout that I'm planning. Any options other than hand laid? Or do you buy bridge track and remove every other tie? 3. While my loco and cars are ho scale (1/87) Klein also has several locos in 1/100 what scale is this actually? Do you use regular HO track for these? (They only appear to be LIKE a double decker unit...but not really double decker) 4. What are your opinions on the Klein products? I bought these while in Austria last month. I'm going back to Europe in the next few months and probably buy some more traction locos. Whose products would you recommend? Whose products would you NOT recommend? I'm a big fan of Electric Locomotives. Thanks in advance.
