Neil,
I do not have the two you quote,so cannot comment,but I have the Liliput and the Marklin versions of the 01.10 and would say that the Roco one is miles ahead in detail than the other two.
But please bare in mind the age of these two
I also have the Merker and Fischer versions,but thats another story(brass and whitemetal)
Peter,
The 01 was the standard 2 cylinder Express loco of the DRG and some were rebuilt after the war by the DB and DR.this is the one you have.
The 01.10 was the heavy weight with 3 cylinders and was streamlined when first built by the DRG.
All this class stayed in West Germany after the war and had the streamlining removed,some were left as coal burners and others were converted to oil,which is the version I have.
These were all based in Northern Germany and lasted until 1975.
The 03 was the light weight version of the 01 and the story of there life is the same as for the 01.
The 03.10 was also a streamliner and were rebuilt by the DB with new boilers,but ownly lasted until 1967.
The DR also rebuilt the ones they got,the as built versions had a problem with the boiler,a few blew up
This is a taster to give you the gist on these Loco's.
David
