Thanks Miguel. I guess this functionality is in part a legacy of the old days when sand layers were usable in previous versions METRo.
I have to admit though that all the roads we work with typically have no sand layers and usually use gravels of various types for the road bed capped with concrete and/or asphalt. Allowing for sand layers should increase the applicability of METRo to a broader range of scenarios; albeit rare ones.

I tried to add a sand layer in the configuration file and I adjusted the code not to have an error message and... it worked! I will update the documentation and, starting from METRo 3.2.2, you will be able to use a "sand" layer.
