Topology Error Check for Lines?

I have a street centerline Feature Class in a File GDB. I did a topology check in ArcGIS Desktop and it identified two streets that are overlapping one on top of the other (each street is identical in length). In FME, I set up a workbench with the SpatialFilter Transformer and two Inspectors to do a topology check. In the SpatialFilter I have tried using all the Spatial Predicates to test one at a time. FME does not call out these two overlapping street segments as does ArcGIS Desktop and ArcGIS Pro.

 

Maybe if I set a Parameter Condition Definition based on Shape_Length attribute field it might work?

 

Fyi, I am using this data as a test to help me improve my FME skills.

 

Any ideas on how to get FME to call out these two streets?

 

Here is a screen capture of the two streets highlighted in red as seen in ArcGIS Desktop.

The Matcher transformer should identify those. It has options for checking geometry.

Thanks! The Matcher worked perfectly.
