This is what my crew and I are experimenting with (thanks to source from the Dutch Train sets).
The Newcastle Flyer that ran between Sydney and Newcastle became a air-conditioned service in 1948 with a 7 car HUB set.
Previously I had each of the 7 cars as separate so buy separate and build your train. That service is still available, but I thought be nice if can buy all 7 carriages in one transaction. Also to have all the different colour schemes available.
If I got my data correct: This image shows the 4 colour schemes of that train.
Top in 1948 was Tuscan Red and Russet Brown.
In 1960 .. Tuscan Red with Buff lining
In 1982 .. Candy Colour
then finally .. back to Tuscan Red with Buff lining.
I hoping to do all NSW country trains like this so can buy all in one transaction. The draw back .. you can not add or remove carriages in the sets. Can only add to the ends.
