can someone tell me why i can't use kato's y switch for a lead to my turntable as space is limited.also on the 15 degree kato xrossing do all ends need to be powered as if wiring for a double cross over.my largest loco are texas,berks and a small 2-6-6-2. any help regarding my issues would be most welcome.this the last stage to completion of my present layout / but yes does it ever end there. regards and later KEWATIN
I have a 15deg crossover, on a temp layout. I'll play tonight and let you know re: the 15deg. Sent from my iPhone using Tapatalk
The rails on the crossings are (electrically) continuous, so you just need 2 sets of feeders, one for each tracks. Which way do you want to use the wye to the turntable? Diverging legs towards the table? If so, you will have some interesting curves to work out. here are a couple of examples of creating a wye interchange, using the Kato Wye 20-222
Does he want a wye to the turntable, or is he just wanting to use a wye switch? Use of rail joiners to the track on the turntable is, naturally, impossible. So, to ensure locomotives don't derail when clunking over that gap and onto the table itself, I strongly recommend all approaches to the turntable be straight tracks nearly as long as your longest locomotive or longest tender (whichever is longest). That's the only reason I can think of why I'd be reluctant to access a turntable directly off a wye switch--I'd be leery of any curve in that spot.
KEWATIN I have a funky "figure 8ish" looped track, with a 15 deg crossover. 1 feeder powers the whole thing fine Sent from my iPhone using Tapatalk
Thanks for your reply,but what i would like to do is run 2 curved tracks parallel to each other much like the kato curve piece to their turntable. again space is at a premium, only because i would like 2 lead tracks to the table. if it isn't possible i do have the space to use just one. many thanks for your time &help. regards&later KEWATIN
It has been done, both by modelers and by real railroads. Just remember that curved tracks leading to the turntable do not help ensure that the locomotive will go from fixed track to the turntable without derailing. Make the tracks as perfect as you can, and use the broadest, gentlest curve you can, and you should be able to achieve reliable operation.
A couple items to contemplate: To create two parallel tracks, straight or curved, it is easier to start with a normal turnout than a wye. Then you either need to simply put a curve off the straight portion of the switch, or create an s-curve off the diverging leg. Tracks leading onto a turntable must always meet the table's circumference perfectly aligned with the bridge (i.e. centerline perpendicular to the tangent). Two parallel tracks cannot meet this necessity
