Train-Li turnouts

Post by nzreg » Thu Jan 23, 2014 9:44 pm

Hello,
I am very new to garden railways and am in the early stages of putting down a basic line.
I recently purchased a left and right hand Train-Li turnout, these are very well made turnouts and should give years of service but there is an issue with them.
This may be normal but I would ask for opinions on this.
The issue is that the point of the frog is higher than the other rails, not by much but enough to cause the wheels of my carriage (scratch built freelance four wheeler) to climb, the other part of the problem is that there is a largish gap between the point of the frog and the closure rail, this causes the wheels to drop by about 1/16".
Is this normal? if not what would members recommend as a fix. The carriage wheels are 32mm in diameter so not in the small category, my worry is that if these wheels drop so much then, other, smaller wheels would drop further.
I welcome any input thank you.

Personally, I've never heard of this brand, so can't speak about the actual product. However, in principle,
Firstly  the rail heads should all all be level, so if the nose is proud there is something wrong.
Secondly, the rails should always support the tyre of the wheel so if there is  major dropping problem then it sounds as though the flangeways are much too wide. In modelling terms this is sometimes dealt with by having a flat filler of some sort at the bottom of the flangeway, so that the flange itself is supporting the wheel at the correct height during the split second it takes to cross the gap - Highly un-scientific and it relies on all your flanges being the same depth which may restrict the number of wheel manufacturers you can use.

Philipy's comments are spot on. Any difference in rail height leads to 'twist' in the ride of a vehicle. A guaranteed trigger for derailment. As usch a hump or a hollow are bad news.

The idea of supporting the flange (rather than the tread) is not entireyl unheard of or unprototypical. It was used in some street tramway turnouts.

Thanks for raising this says a man poised to buy a train line 45 point. I want to lead a loop into a station from an existing trainline curve. This would obviously be an easy fit and I may be committed as the radius r2 isn't a match to lgb. I'm having running problems with aristocraft and was hoping that was back to backs.
Perhaps I should have gone 32mm :?

Thanks for the replies all taken on board.
I must say that placing these turnouts on a temporary layout and running my only loco through them at a variety of speeds the loco does not derail.
I have written to Train-Li and hope to receive a reply next week, I will post the findings.
