Double deckers are the norm with diesel locomtive pulled/pushed trains. But single level DMUs are the norm in North America.
The correct choice depends upon predicted ridership 20 to 30 years into the future. Bi-level Bombardier cars have ~150 seats, a 10 car train has a capacity of ~1500 seats. Standard single level DMU articulated cars have ~100 seats, double articulated DMU cars have ~150 seats, but being limited to a maximum of 6 car trains, their maximum capacity is ~600 and ~900 seats.
Station platform length is usually the determining factor on the number of cars in a train. The 6 car DMU maximum limiting factor is based on train multiple unit controls and coupling capability.
Colorado Railcar was recently liquidated and was the only manufacture building heavy (FRA compliant) DMUs. But there are other manufactures that may start building them soon. Somona-Marin Area Rapid Transit is looking at buying DMUs soon, and has an interesting presentation about the available choices.

FRA Compliant Heavy DMUs:
1) Bombardier M7 Designed for commuter service mixed with freight, Married pair configuration, Design base: LIRR M7 (FRA compliant), Diesel electric drive, No cost estimate available.
2) Nippon Sharyo Designed for Commuter service mixed with freight, Married pair configuration, New Design, Diesel hydraulic drive, No cost estimate available.
3) Rotem Designed for commuter service mixed with freight, Married pair configuration, Design based on TTA project, Diesel hydraulic drive, ROM cost estimate $8 to $9M. Note: In August 2006, Triangle Transit (formerly Triangle Transit Authority) announced that it would not file a “New Starts” report on the Regional Rail Transit Project with the Federal Transit Administration (FTA) for Federal FY 2008.
Triangle Transit, the Durham-Chapel Hill-Carrboro Metropolitan Planning Organization (DCHC), Capital Area Metropolitan Planning Organization (CAMPO), Triangle J Council of Governments (TJCOG), NC Department of Transportation and Regional Transportation Alliance will work with the community as we rethink transit in the Triangle.
4) Siemens No information available (Siemens exhibits interest in building FRA-compliant DMU)
5) CAF No information available (CAF offered an FRA-compliant DMU to NJT)
Non FRA Compliant Light DMUs:
1) Alstom Coradia Lint 41 Compliance UIC; EN 15227 Germany, no US application
2) Bombardier Talent VT 643 Compliance UIC, Germany, Ottawa Canada, no US application
