FCC contact for railroad equipment
Could someone provide me with a contact within the FCC (or any other authorized agencies) that deals with FCC rules applicable to railroad devices (locomotive and wayside)?

definition of type certification
Forgive me if this is a naive question (given my background of compliance to MIL-STDs), but I keep hearing references to type certification which seems to be relative to generic FCC, ACA, etc. type compliance testing of comm devices. I am more familiar with references to specific FCC Part 15 or other ... are these references synonymous? Susan H.

info on AS4295

232 vs. 422 for CM rejection and noise immunity
I am in need of some outside advice regarding 232 and 422 interfaces. Could someone please confirm which interface supports a difference of 50' between devices that could have greater than 100 volts potential difference between the grounds? Thanks in advance. Susan H.

separation to meet 2000 VDC hipot
I recall many messages regarding trace separation, etc. to meet certain voltage isolation requirements; however, none of those specs are applicable to my products. Is there a general guideline for separating traces to meet isolation requirements and survive a 2000 VDC (input to chassis) hi-pot requirement? I have heard that using 25 mil separation is a rule of thumb ... accurate? Susan H.

IEC 571-1
Does anyone have info on IEC 571-1/90? Our customer is refering to this document as the EMI transient specification most applicable to our railway program. I'd like to learn more as to why it is applicable and also how this spec compares to the one to which we've already tested (IEC 801-5).
