The Tasmanian Main Line Company (T.M.L.) was a privately owned railway company that existed in Tasmania from 1872 to 1890. The company were the first operators of rail services between Hobart and Launceston, where it connected with the Launceston and Western Railway (L.W.R.).

PS Appears to be a late strike?
Pmk shown in the link suggests last day of use =1908 !

Thank you Rod , interesting read.

John Hardinge's book 'Tasmanian Postal History: The Post Offices and their Datestamps' gives the latest recorded date for T.M.L Ry No.1 as 3rd February, 1912.

In Tasmania : The Postal History and Postal Markings Part 2

Avery, Edwards , Ingles and Purves suggest 20th February 1912 (Page 134)
But I felt is was open to interpretation, they, bunching the TML 1,2,3
in one quote.
That was back in 1975

The Tasmanian Philatelic Society 2008, offered a NIL Rarity factors, to any of the 9 TPO Datestamps, found on Tasmanian Pictorials.

Rod, yes, Hardinge's book (2018) still has the LRD for T.M.L Ry. No.2 as 20th February, 1912.

What is a NIL rarity factor? Is it really nil, which means minimal or nothing?

Hi Orstampman,
no nothing like that, just means reasonably common.

Roughly speaking
Factors may go something like RRRRR 1-3 copies or, Known but not seen.
RRRR 4-10 copies
RRR not often seen
RR scarce but not rare
R limited numbers
Blank (Nil) reasonably common.

Differing Authors . societies have their own rating systems.

Thanks, rod222, great information.
