SLRG History Questions

I am interested in learning more about this honorary narrow gauge.

What is the southern terminus of the SLRG? The northern terminus?

Is this a publicly traded/owned company or privately owned?

What is the total amount of trackage owned/operated?

What are the main communities served?

What are the main sources of traffic?

Has traffic increased sense transfer of ownership from the UP?

Any future plans to further expand service and if so what types of service?

Does the SLRG own its motive power or lease it?

Besides the 1744, what is the motive power being operated.

Thanks for the answers!
