A system for transferring railroad cars from incoming receiving tracks to classification tracks for building outgoing trains includes a plurality of incoming receiving tracks, a plurality of outgoing classification tracks and one or more transfer tables for moving railroad cars from the incoming receiving tracks to designated outgoing classification tracks. Each transfer table has a plurality of track segments. Incoming railroad cars are received on a plurality of incoming receiving tracks. A first car is uncoupled from a following second car on each of the receiving tracks having cars. The uncoupled first car is moved from the incoming receiving track onto a corresponding track segment on the transfer table. The transfer table is moved to align a selected track segment with an appropriate classification track for the corresponding railroad car. The transfer table is moved and aligned with appropriate classification tracks until each railroad car has been transferred to the appropriate classification track. The steps are repeated until all of the cars have been classified and transferred to classification tracks or held back for later transfer.

1. A method for transferring railroad cars from incoming receiving tracks to classification tracks for building outgoing trains, the method comprising: a) providing a railroad yard comprising: a plurality of incoming receiving tracks;a plurality of outgoing classification tracks; andat least two transfer tables for moving railroad cars from the incoming receiving tracks to designated outgoing classification tracks,each transfer table having a plurality of track segments;b) receiving incoming railroad cars on a plurality of incoming receiving tracks;c) uncoupling a first car from a next following car on each of the plurality of incoming receiving tracks having cars;d) moving the uncoupled first car from each of the plurality of incoming receiving tracks onto a corresponding track segment onto a first transfer table, whereby the next following car becomes a first car on the incoming track until there are no more following cars;e) moving the cars on the first transfer table to a second transfer table;f) moving the second transfer table to align a selected track segment with a classification track for the corresponding railroad car on that track segment and transferring the car to the classification track;g) continuing to move and align the second transfer table track segments with classification tracks for the corresponding railroad car on that track segment of the second transfer table as set forth in step f) until each railroad car has been transferred to a classification track;h) while steps f) and g) are being performed, transferring the next first cars from the receiving tracks to the first transfer table; andi) repeating steps c) through h) until only one car remains on the incoming receiving tracks and repeating steps d) through g) for the last car so that all of the cars on the incoming receiving tracks have been classified and transferred to classification tracks or held back for later transfer. 2. The method of claim 1, wherein the transfer tables are magnetically levitated. 3. The method of claim 1, wherein the railroad yard further comprises a trackway below or adjacent to the incoming receiving tracks, and the method includes positioning an uncoupling device on the trackway to uncouple the railroad cars for moving onto the transfer table. 4. The method of claim 1, wherein the railroad yard further comprises indexers positioned for use on the track segments on each transfer table and on the outgoing classification tracks for moving the railroad cars, and steps e and f move the railroad cars by means of the indexers.
