<br />7.A <br />Page 24 <br /> <br />. Less safety issues <br />. Traffic freedom <br />. Allows for freedom of movement and land use does not divide city <br />TrenCh (covered/uncovered) <br />. Allows for free flow of traffic and community activity <br />. Allows for building above <br />o Parks, living areas <br />. Allow for diesel fumes to escape <br />. Most feasible <br /> <br />2. What would be the challenges of each of the track placement options? <br />. Aerial <br />. At-grade <br />. Trench (covered/uncovered) <br />. Tunnel <br /> <br />Group 1- challenges <br />Aerial <br />. Integration with at-grade <br />o Especially for heavy freight cars <br />. Noisy <br />. Safety concern with derailment <br />. Earthquakes (especially with freight cars and hazardous freight) <br />. Any station would be up in the air <br />Open Trench <br />. Connectivity is reduced <br />. Vandalisml terrorism! suicide <br />. Maybe fences will be necessary, with visual impact <br />. Flooding <br />. Water table <br />. Large construction right of way impact <br />Covered Trenches <br />. Egress safety, train safety <br />. High cost <br />. Most disruptive for construction <br />Deep Tunnel for HSR <br />. No HSR station <br />. They won't pay for Caltrain grade separation <br />. Caltrain at-grade, noisy <br />. Expensive: could kill the project <br />HSR Covered Trench I Caltrain Aerial <br />. Separate train infrastructures - hard to change between HSR and Caltrain <br />. Difficult construction <br /> <br />Group 2 - challenges <br />
