As of Nov 14th Tacoma Rails has taken over operations on the ex-Tacoma Eastern. By taking D St and truning left just after crossing the tracks you can follow the road to Ruston. The line goes through the Nelson Bennet tunnel at this point. Along the way you'll pass the grain elevators. All the units are radio controlled and have some unusal spark arrestors.
Access is limited but worth a look.
Full and empty grain cars are spotted at the old NP Halfmoon yard. On the bluff over looking this yard is the old NP office building. At 11th street BNSF's Lakewood sub leaves the main and goes through the streets of Tacoma and up Nalley Valley and to Fort Lewis. Here's a radio freguencies that might come in handy. I will be adding train operations to this page shortly.
