Model Railroad Operation: TAC system

I have been thinking a lot about my SVNO and Model Railroad plans as of late.

It seems that the most common way for model railroaders to 'operate' their model railroads these days, is to utilize a 'car card' system. This is a system which closely follows prototypical operations, and includes cargo type, and equipment cards, for each rail car on the layout. As well as waybills listing where the car came from, and where it is going. Very detailed, yes.

Aquarium: Week 8

Time for a week 8 update!

Week 8 begins with the following readings:

Salt: Measured at 1.024 - added salt slowly into the flow, and now at 1.026
Temp: 78
KH: 9
Calcium: 500
Phosphates: 0
Nitrates: 0

Aquarium: Week 7 - More Control Automation Planning

Week 6 went by well, and Week 7 is upon us. I purchased more hermit crabs, and snails, and have also purchased a Coral Banded Shrimp, and a frag of Torch Coral. The crabs and snails have been doing a great job, but just can't handle the whole tank.
