#ThePermanentWay | LESSON 4: vertical geometry

Here's the fourth lesson in #ThePermanentWay series, using Cities:Skylines to explain permanent way (and wider railway) concepts... Today, we are looking at turning our 2d plans of railways into 3d railways with a z dimension. When is a railway too steep, when does vertical geometry get complicated and what is a vertical curve? Watch and find out! Enjoyed this? Please do consider supporting me at patreon.com/garethdennis or throw loose change at me via paypal.me/garethdennis.

Really enjoying this series! Makes me want to fire up that copy of Cities Skylines I bought but never got into. I'm curious as to what design software you use in the day job. Is it rail industry specific or just cad and civil 3d like the rest of us?

It's a mixture of tools within the Bentley suite: MicroStation as the overall CAD package, then primarily Rail Track (derived from MX and InRail, in turn derived from MOSS which is an ancient package from the mid 1970s developed by British councils back when they had money). We also use another tool called ClearRoute for gauge clearance analysis (it's now owned by Balfour Beatty). Plus many other tools for tasks like asset monitoring or measurement, whole life costing, etc.

Excellent. Was very busy at work and now all messed up with the order but enjoying. Good to hear mention of the Lickey incline!
