Pictures of concrete/wood junctions?

[gavino200]

I'm using concrete tie track for my station. That means I'll have to paint some junctions. I recently learned that the Kato single crossover junction was prototypical with a combination of concrete and wood ties. Apparently the wood allows the workmen to improvise with the complex portions of the junction. 

 

My station will have a double crossover and two different types of Kato points. Does anyone know how a prototypical japanese version of this would look with concrete ties? Would it also have some of the ties made out of wood?

 

Same question for the regular junctions/points.

That single crossover is synthetic ties, not wood ties.

Remember a lot of lines with concrete ties have the concrete ties added in as the wood ties wear out.  In Kyushu on the sasebo/omura/nagasaki lines this has been a gradual process, I believe every second or third tie is concrete now on older track.  Switches seem to stay wooden and only get concrete ties if the whole turnout is replaced, and often seem to stay wood for the reasons you mentioned.  The brand new Nagasaki elevated station just opened a few months ago and has wood switches while the rest of the track is concrete ties or slabs.

It is plausable to have a mixture of different ties.

 

Wood was the original, shifting to steel, then concrete and onto synthetics.

 

Steel was short lived.  It was cheap but a pain to pack the ballast underneth correctly and didn't weight much so the track you shift and require extra remedial work to fix.

 

Concrete fixed this issue and has longer lifespan than the both above.  But the casting/molding process was hit and miss, but the much longer lifespan of concrete tie.  Any holes and/or different length in ties then required meant these would need to be orginsed in the casting/molding stage, hence wood was kept for turnout.  Drilling holes in concrete normally led to cracked ties.

 

The reason wood was kept was long ties could be cut to any length with ease using a saw.  Holes could be drilled easily without cracking.

 

Now we got synthetics.  Same benfits as wood, but you don't chop trees, and lifespan is much longer.

 

Depending on the time/era you choose to model, will depend on the amount of each you will see on a railway.  And as the above poster has mentioned.  Some less travel rural regions are much slower to recieve updates and the remedial work is done less frequent.

I'd suggest they are synthetics.  The end of the line at Nagasaki are synthetic ties.  I'd guess the turnout to be the same.

Yup synthetics

So all the regular length ties would be concrete and all the longer ties would be that crimson/brownish color?
