If I recall correctly, the original TS2009 only had these regions:
TS2009 Surveyor provides these 7 regions:
Default Region,<kuid:-1:78032>
Australia,<kuid:-1:7801>
United States,<kuid:-1:7804>
France,<kuid:149301:1003>
HP-Trainz Region Elbtal,<kuid:68787:1266>
SDW.2.1 Region Thuringen Romantik,<kuid2:121616:100901:1>
PTP Region,<kuid:151900:1>
The UK region (<kuid:-1:7803> comes in one of the SP patches. Have you updated to the latest patch?
