Thanks everyone for all the advice. Really appreciate it! Concerning the minimus radius of 054, about 7-9 years ago I bought all new 072 Lionel Fastrak. I was running my original trains on 50+ year old Lionel steel " O Gauge" track that would cut up my hands, come loose, etc. And I got fed up. When I discovered the new track systems I settled on Fastrak and am glad I did. 072 looks great so the decision was easy. Plus I have plans for big steam and big diesels one day. One day...
I may get myself banished from this forum forever, but I was happy to throw all that old track in the trash.
