Calvin (from Calvin & Hobbes) sitting at a lemonade stand, smiling, with a sign that reads, "Trains and micromobility are inevitably the future of urban transportation, whether society wants it or not. CHANGE MY MIND."
A place to discuss problems of car centric infrastructure or how it hurts us all. Let's explore the bad world of Cars!

In the absence of a flair system on lemmy yet, let’s try to make it easier to scan through posts by type in here by using tags:
Wheels are 100% different on Heavy Rail, Metros and Light Rails.
In addition to that all 3 have different requirements for curves, runout and grades.
Source: my employer makes all 3.
Wheels mostly not. Though bogies for LR and everything else are very different.
And by wheel I mean steel disc, not breaking system, not suspension, not everything else.
A lot of light rail uses resilient wheels and heavy rail does not.
Wheel profiles (the shape of the part that actually touches the rail) are also very different between different categories.
Huh. Today I learned.
