While in UK I purchased a PECO N gauge right hand turnout plus two pieces of connecting track. The three were supposed to fit together, although I did not try this in the shop. When I try to add two pieces of track to the through route and the diverging route, the large plastic pieces (sleepers) at the ends of the two pieces of track get in each others way. I can get them to connect by cutting away the brown plastic, but I am sure this is not what was intended. Any suggestions on what to do will be appreciated. Thanks in advance.
The two pieces of connecting track look like Atlas. If you're mixing Atlas and Peco, how can you be sure what "was intended"? Atlas intended for you to use only their track. The hobby shop intended to get you fixed up with compatible rails of the shape you needed without making you wait for special orders. Any part of the ties not between the rails is intended to look right, and serves no function. If they had separate tie molds for "switch on left, one end", switch on right, switch at both ends with left-left, left-right, and on and on and on those things would have to cost €50 because of special ordering and handling. Instead, we are trusted to be modelers and hobbyists, and competent to operate a sharp knife. Trim the edges of the ties and don't worry about it.
A couple of features. One, because Peco switches don't extend the track as far past the frog as Atlas switches, your double track is spaced closer together, which is realistic. Two, you get to play with a sharp knife, and that makes a real model builder out of you!
Well, Atlas didn't intend anybody to use only their track although it is reasonable to assume they would LIKE everybody to use their track, as any supplier would. They intended their track to be compatible with almost all other N gauge track, which it is, within reason. All brands have their idiosyncrasies with fitting. Doug
You just ran into an old problem all of us have had. When working with Peco (my preferred track switches) I keep a Dremel Tool handy and cut off the overhanging ties/sleepers. It doesn't look bad and it works amazingly well. What I was afraid you were saying is the Peco track didn't fit into the Peco switch. As in a different gauge. That can happen with older pieces of sectional track. Once again the Dremel Tool or any other cutting tool will help you get your track lined up and joined together. Everything normal.
At least it's not UniTrack's #4 switches. Anything but their included, shaved straight pieces on at least one of the branches requires trimming the attached roadbed! I wouldn't want to void the warranty on my Xurons' doing that...
