Hi
All good information , some i already knew but useful anyway...But it was not what i meant to ask, so i will try and word it a little different if i can.
I know the protype measurements and if p4 had been Hornby's choice all those years ago , and if peco had then not complicated it by creating more compromise by setting streamline a 50mm track spacing, things would have been a simple translation.
On the existing parts of AV, i stuck, mostly to steamline 50mm space, however i messed up on the four lanes of kalborough, because at the time I did not know about the 10 ft, i am stuck with that for the time being as i will not rip it up until the rest is finished,
The one thing that was a pain, is that things like Dapol catanery are not spaced for streamline track....go figure.. Nor are skaledale bridges, Bachmann crossing, scale scenesheds, the list goes on.
So regardless of what the theory would say is correct, i was really trying to understand, have others found this a pain too, and if so how did they handle it.
I am thinking, 50mm and widen when i need too, bit like the real thing OR..... Set track spacing and thin when i come to complex junctions.
Before i started i was just wondering how others compromised on this.
As i say all good stuff and it is a good topic of conversation which is good to continue, but it is clear i did not ask the question properly, so sorry about that and if any one has any views on the refined question too, it would be useful.
