Can we all agree that SSL either means Sightseer Lounge OR Sunset Limited? Sightseer Lounge would seem to make a lot more sense since we already have cars with accepted three letter acronyms (PPC, CCC, etc) and numerous trains that have accepted two letter acronyms (CS, CZ, EB, etc) but I'm fine either way so long as it only stands for one and not the other.
It's always clear in context what it means, no?
You don't say the SSL is running late and mean a self-propelled lounge car.
You don't say the SSL was bad-ordered and mean the Sunset Limited (tho I suppose it's theoretically possible that an entire consist could be bad-ordered).
BUT in the interests of clarity, you could write SsL to mean Sightseer Lounge and SSL to mean SunSet Limited or sSl to mean sightSeer lounge and ssL to mean sunset Limited or vice versa or one and a vice vice versa for the other.
Or maybe the SSL (for Sunset Limited) could be written LSSL for Limited Sunset Limited since it's limited to three days a week.
But what do I really know? I always thought that the CCC stood for the Civilian Conservation Corps! (which might make sense to the three people on this site whose knowledge base perhaps might go back to the 1930s...)
And why stop there? Why is the LSL not the LL because lakeshore is one word? Or alternately, why isn't the CS not the CSL because even though starlight is one word, why should it be treated any differently than the SSL or SSL or LSL? And shouldn't the Cascades just be the C train? And the Pacific Surfliner the PSL?
And you, Texas Sunset, are you just TS or TSS?
Inquiring minds (with too much time) on their hands want to know.
Submitted to you without any acronymony whatsover.
