Mattapan Ashmont progress

Had some free time over the long Presidents Day weekend so I was able to make a lot of progress on the Mattapan Ashmont trolley. I finally got the ramps south of Ashmont station done which were a bear because I didn't quite get the radiuses right on the ramps to fit the 30d Tram Curve I was planning to use and had to fall back to some dynamic track to get it all to fit.

Once I got past that I was off and running to Cedar Grove, etc. The track went smoothly, although I found I had not put down enough markers so had to go back to Google earth and lay down some more. Got all the track laid including Mattapan Yard. I had to make one compromise in the yard layout. In order to prevent an issue with creating activities I left a section out of the return loop, otherwise the line would loop forever. You can come out of the yard and go into service, run to Ashmont, loop and run back to Mattapan but then you have to terminate there as the inbound side does not connect to the yard. I think that still allows for some reasonable activities.

I also decided to start doing some scenery as I go rather than waiting until all track is done then doing it all at once, so I started adding sceenery around Cedar Grove, the cemetery and underpass for the NHRR branch, lots of trees, a few houses. I need to find or build some New England style houses e.g. triple deckers.

Onme setbak was that I had downloaded a package for building the overhead but it doesn't fit, seems to be designed for a single track line and the poles are too close together. Plus they are wood poles and the Mattapan line uses metal poles.
