For this section we need to move from Binns Road in the city of Liverpool on the coast of North West England to Richmond on the edge or London , to a firm called Rovex founded in 1946 by Alexander Venetzain a toymaker, Rovex where a precision plastic maker, in 1950 they launched a train set in OO gauge the locomotive being the Princess Elizabeth along with 2 coaches and teack, the set had plastic body shells, plastic sleepers etc, differing from Hornby Dublo that at the time used metal for most parts.

The trainset lasted several years, however the Rovex name on the box lasted no more than a year as Rovex was very quickly taken over.

Lines Brothers had been around almost as long as Meccano Ltd. Launched by 3 brothers, William, Walter and Arthur Edwin Lines, sons of a Victorian Toy maker. As 3 lines make a triangle they traded under the triang brand name making large metal children's vehicles. However following World War 2 the company was keen to get a share of the expanding model railway market. In 1951 they took over Rovex Ltd, renaming the OO Railways as 'Triang Railways,' and building a new factory at Margate Kent which was ready to take over production from the old Rovex factory at Richmond in 1954.

 

Triang railways was aimed at the lower end of the market, under the price of Hornby Dublo, this made it popular with parents for children's christmas and birthday presents thus depriving Hornby of a vital market, Hornby at the time where aiming clockwork O gauge sets at this market. The use of plastic meant also that Triang could provide better details than their metal Hornby counterparts thus appealing to those who wanted better details and was prepared to abandon Hornby.

Through the 1950's and early 60's Triang expanded their range By 1962 the range had expanded to 25 locos, as well as rolling stock and a new range of buildings called Model Land being introduced in 1963

In 1964 Triang took over the ailing Meccano Ltd including Hornby Dublo thus eliminating their main rival. In 1965 Triang launched Triang Hornby in theary a combination of Triang Railways and Hornby Dublo but in practice it was 95% Triang and 5% Hornby, This new name was to be the name that dominated British model railways for the next decade. In 1967 a limited rival of the Hornby Dublo range when another part of the Lines Group, G & R Wrenn bought the Hornby Dublo castings and started to produce the locos to be sold along side Triang.
