I got my first lego set at the age of 5 in 1960. I have recently been modelling Union Pacific in HO (not lego, but expensive digital stuff with sounf) but with a clutch of grandchildren arriving I'm looking for something more accessible to share with them so the HO stuff is on ebay and I'm back to lego which survives contact with children under 11. So I have an Sbrick and I'm looking at Bluerail. ME Models and a guy in Poland - trixbrix.eu - are making less toylike track and there are lots of designs for recognisable Union Pacific prototypes in 6-wide and upwards so the future looks bright and all my prototype data still has value. Anyone else out there wanting to run prototypical operations using Lego rolling stock and track?
