So far I haven't seen any pictures of electric units pulling or pushing bi-level passenger cars, only single-level cars (ex: Acela). Is it considered impractical or inefficient to conduct such an operation?
I'm wondering, because, say a commuter rail system dependent on diesel units wanted to electrify its tracks, could they just purchase new electric units to pull/push their existing gallery/bi-level cars? Or would such an agency be better off just purchasing new single-level cars, maybe even electric multiple units (single or bi-level) for speed/acceleration efficiencies?
Thanks in advance.
