I just today started playing around with the SCARM software. Hard to teach an old dog new tricks so this will probably be a easy question for you guys, probably right in front of me but danged if I can think of it so here goes:
When designing with Lionel Standard Gauge Track...the first three pieces listed are 7" 2T and 14" 4T and 14" 6T.
What is the difference between 14" 4T and 14" 6T?
What does the "T" stand for (Ties?)
Probably the first of many foolish questions!
