Help:VE271

The specified TCB flags are invalid, please check the wiki for valid configurations.

The track circuit block (TCB) detector flags on this asset include an invalid combination. TCB flags are given as a semicolon-separated list and fall into two groups:

• Traffic type - E.g. 'Freight', 'Passenger'. These may be combined with each other and with any track type.
• Track type - E.g. 'MainLine', 'BranchLine', 'YardShunting', etc. These may only be combined with each other in certain configurations.

The following track type combinations are not allowed and cause this error:

• 'MainLine' cannot be combined with any branch-line type ('BranchLine', 'Siding' or 'Spur').
• Yard types cannot be combined with other track types ('MainLine', 'BranchLine', 'Siding' or 'Spur').

You may combine multiple flags within the same group - for example a block can be both 'YardReceiving' and 'YardDeparture'.

To fix this error, correct the flag list so it does not mix incompatible track categories.
