Sometimes one element inspires and defines a starting point for a model. This time that element is a special windscreen.
Built around a windscreen, Psi is a low-profile DMU passenger train. Extremely tubular in exterior form, the body style borrows from the Japanese JR500 series, yet the nose blunts abruptly suggesting low-speed and strength. (Concept Psi is an imaginary passenger train design. It is not based on any particular real-life train, even though the cylindrical form is familiar in the JR500.)
The wheel configuration is a common 4 axles per car employing two 2 axle trucks. Dual front and rear driving cabs relieve turn-about requirements at end-of-line station stops. However, extreme nose overhang prevents multiple train set coupling; thus, heavy revenue routes require the addition of non-driving-cab cars.
The Psi set shown here received a coloring scheme inspired by historic liveries in the USA's Amtrak stock.
Still on the drawing board, Psi has yet to be real-brick-built and tested on-track.
