A real mountain ridge runner line,beautiful! Must be a real headache when winter hits,as there seems to be a lot of deep cuts,and extensive tunnels! Query; is there a base hourly service,or half hour? Secondly,how long is that line,in miles,and there must be a couple of 2or 3% grades! Again,thank you,for showing an interesting former mainline! Always new material,that I didn't know about! Thank you 😇!
