Once the maximum train length and trains per hour at a station are achieved, then double decker cars are the only way to avoid building new rail lines. This is usually done by putting the lower floor between the wheels, closer to the rails, and then adding an upper floor above.

Capacity improvement and station length


Once the maximum train length and trains per hour at a station are achieved, then double decker cars are the only way to avoid building new rail lines. This is usually done by putting the lower floor between the wheels, closer to the rails, and then adding an upper floor above. This design fits under more bridge
Bridge

) and lowers the center of gravity. There are two basic designs for bilevel cars. High platforms use "split level" design. Low platforms use "two floor" for level entry onto the lower floor. Occasionally a third, very tall "two floors over-wheel" design is used. This is a traditional single floor car "with a second story" design with steps from low platforms up to a traditional floor height.

Platform height and floor height issues


There are four important height measurements above the railhead: platform height

 matters for end doors connecting to existing single floor rail cars. Downstairs or lowest floor height is primarily determined by the thickness of the beams connecting the span between the wheels and bogies (trucks) of a rail car. The upstairs floor or highest floor height is above the lowest floor and must fit under bridges and tunnels. Level entry floor height must match the platform height. Hopefully either the traditional or downstairs floor height already matches the platform height. Despite the name "bilevel" or "double decker", for maximum compatibility the rail car will have up to four different floor heights. Using outside steps to avoid having a level entry from the platform is troublesome.

 with stairs inside the car for the upstairs and downstairs double decker floors. These cars are designed for high platform rail line, such as all the existing stations with a standardized high platform and the rolling stock end doors that connect to any traditional single floor car and even roof line aerodynamics. There are three floor heights (upstairs, downstairs, and platform levels) in these "split level" cars. The entry level floor area has to be big enough to hold wheel chairs, children push-carts, and even wheeled luggage. This high platform "split level" double decker design is the preferred design in urban and commuter applications, and can be designed to matched to any rail platform height

 double decker trains have level entry onto the lower level of the car, allowing wheelchair access. There are two floor heights (upstairs and downstairs) in these "bilevel" cars. There is a staircase between floors inside the car. Connecting doors between cars are at the (higher) upper floor height and not at the traditional height. These low platform cars use low platform stations across the Western US, because the traditional single floor trains all had exterior entry steps to maximize flexibility (emergency and temporary stops) and minimize infrastructure costs. There are no examples of two floor platforms, so there are no platform doors on the upper floor. Car roof lines lengthwise are flat for connecting doors to the upstairs of bi-level cars. Connecting directly to a single level car causes drag and connecting door problems. Bombardier Amtrak Superliner is tall.

Uncommon Very Tall Design


There are several very tall bilevel cars (e.g. Colorado Rail has or 6033 mm). They typically are described as a traditional rail car with a second story. Most of these cars serve low platforms so have exterior steps up to the traditional "over-wheel" floor height (e.g. US . End doors connect at the traditional height of existing rolling stock. Some cars have upstairs end doors as well. Upstairs and downstairs connect by interior stairs. These cars can fit the most able people, but lack level entry. Some cars are self-propelled Multiple Units so using traditional floor heights appears fixed. In towed cars it is possible to lower the downstairs floor between the wheels/bogies so that level entry is possible with more than 500 mm of added headroom and interior steps from that floor to the traditional floor.

Containers


Similarly, one may also have bilevel cargo transport. In intermodal freight transport

 well cars cars are designed to accommodate "double-stacking." Where passengers and freight rail use the same lines, containers may have required increasing the lines structure gauge. But passengers and freight are usually separated. Containers are wide and tall or sometimes tall. Therefore double stack freight is 17, 18 or above well car floor height.

Alternatives


The alternatives to double decker cars are usually explored first, before going double decker.
  • Add cars to existing trains: this works until platform and siding capacity has been used. Until that occurs, lengthening trains is preferable to changing the loading gauge

     of the rail line. Longer cars (without changing structure gauge) does not add much, because cars are often required to be narrower to negotiate curves. In countries with larger structure gauges for freight traffic (such as the United States) this is often less of a concern.

  • More trains: increase the frequency of trains scheduled. This added flexibility compared to the same capacity via bilevel cars is generally very popular with passengers. However, it may cause congestion on the rail line, eventually preventing more capacity from being added in this way.

  • Changing seating: fitting more (smaller) seats into the same space and/or decreasing the pitch (distance between seats) on existing vehicles.

  • Track amplification: building additional rail lines and platforms is expensive and often requires land acquisition and service disruptions.


If freight service has increased the structure gauge, and the rail line needs to minimize "per car" maintenance and staffing costs double deckers can pay for themselves more quickly than buying single floor cars of equal capacity. Wheelchair accessibility laws encourage level entry solutions frequently provided by double decker rail cars. Profitability is encouraging double decker rail cars adaptation before many alternatives.

In Japan, however, double decker commuter trains are relatively fewer than those used in Europe or North America. This is because Japanese commuter trains can be much more crowded than Western counterparts. Therefore, they generally need more standing spaces than seats. Also, Japanese train cars are 20 m long or less, and it is technologically difficult or inefficient to have more than 2 doors on each side of double deckers that size. Japanese crowded trains, however, generally need 4, 5, or 6 doors on each side to make smooth boarding and alighting.

Gallery cars




Because of the two levels being separate on most cars, there is a physical limitation on the conductor, as it is difficult for him to verify, collect payment and sell tickets to such a large concentration of passengers in one car on each level, owing to the sometimes short distance between stops.

A solution came in the form of the design of the "gallery" car, which featured upper levels, which were really mezzanines
Mezzanine (architecture)
In architecture, a mezzanine or entresol is an intermediate floor between main floors of a building, and therefore typically not counted among the overall floors of a building. Often, a mezzanine is low-ceilinged and projects in the form of a balcony...

 running along both sides of the car, with an open area between the mezzanines. This enables the conductor(s) walking along on the lower level to easily reach up and punch or validate tickets of the passengers seated on the mezzanine level.

Passengers can place their tickets in clips along a lengthwise panel, located slightly above the conductor's head and within easy reach. The conductor can then quickly check tickets and move to the next car.

Another advantage of bilevel gallery cars is the relatively low first step of the vestibule entrance to the car, which is above the head of the rail. The advantage of this is that commuter rail operators do not have to spend funds on building high-level platforms; a low-level platform is all that is necessary, at a far lower cost. This can be a major disadvantage as well, as many commuter rail systems prefer high-level platforms as they can decrease loading and unloading times substantially, and greatly improve access to trains for the disabled.
