Just read with interest Ed Boyle suggestion for grading electronics in trains. I sent him an e-mail and I am also starting this thread with a suggestion (haven't seen a thread on this yet unless on page 3 or later) on loosely aligning his ideas with TCA grading standards. Should also include other cars that have electronics like Coors beer train cars and control systems.
For Instance suggest this lineup:
E10 - Electronics as delivered from manufacture and fully functional, no changes except replacing consumables with same type if still available (e.g. no BCRs replacing NiCd)
E8 - Electronics original as delivered, but partially or non-functioning.
E5 - Electronics replaced with different system. (DCS replaces TMCC, DCC replaces manufactures boards)
E3 - Electronics removed, replaced with simple electronic or mechanical E unit
E1 - All electronics removed, motors and lights wired direct to rails (bridge rectifier and capacitor with no intervening control electronics)
As you see, I left holes in lineup to add or re arrange the ordering, but not to finely split hairs. For instance should board sound files and firmware upgrades still be E10, or maybe made as a new E9 grade? What do we classify engine when PS1 boards no longer available or repairable and forced to use PSxx replacement is it E5 or new grade E6 or maybe E4?
Suggestions welcomed!
