As shown in the drawing', all parts are m the normal condition, that is, eachof the track secl tions is unoccupied, each or theswitches W isV in its normal position, and each'or the push but#A tons P is in its normalv position. fWth the track sections unoccupied, eachof the-relays.

Accordingly, the despatcher will momentarily depress push button-P3 while a trainman is depressing push button P2 after having opened the door of the case associated with W2 thereby closing contact f2.

Relay L2, upon becoming energized, opens its back contact 12, therebyinterrupting thecircuit for relay K.Y Relayv K 'becoming 'deenergized the contact 13 of this relay'will'open, and eitinguishI r indicator lamp/e, thus indicating to thev despatoh-v er'the energization of relay L2. The ,deenergizael tion of relay K also causesits contact 14 toopen in the circuit for relay H, which is, liov've'ver,` already open on 'account of relay R2 being deenergized because the train is in'rrsection B-C preparatory to moving over switch W2 reversed.
. Relay R2k lbeing deenergized,Y magnet d for switch W2 will -now be ienergized by a circuit passing from terminal throughcontact 190i lever V2, contacts k20 and-2l of relay L2, contact 11 of magnet d.v
switch 23 of' rel-'ay R2, andthe winding of magnet dito terminal o. Theenergization of magnet d opens its contact 11 in the circuit for relay K, which is, however, already open at contact l2 of relay L2. With'magnet d energized, dog 26 will be out of engagement with knotch 27 of 1the corresponding segment, and hence the train'man can move leverwV`2 to-withdraw dog a from bar b. Thetrainman can then proceed to reverse switch W2- The reversal of switch W2 opens its contact 10 in the circuit for relay K, which is, however, `already'open at contact l2 or relay L2 and at contact It, after the train has moved into siding Z2 and has cleared track section C-D, permitting relay R3 to become energized, the trainrnan returns switch W2 to its normal position and, further, as-
suming that the other track sections shown in the` drawing are all unoccupied, the apparatus will be returned toits normal condition previously described, provided the door of the casingV has been closed. Y Y Al.willnow-'assume that afterwards the trainis ready to leave siding Z2 and to continue its movement' westward. The trainman will-notify-the sov despatcher by .some suitable means, such-for example as a telephone, that the train is ready,-and
the despatcher will again momentarily depress push button P3 while the .trainman depresses push button P2 and! opens the door of the casing, for
causing relay'L2 to again become energized. Relay'L2,.upo`n becoming energized, causes .magnet dito become energizedy by'aV circuit which is the same as thecircuit previously traced, except for including-.a branch path through front contact 22 of relay T122, .around contact 23 of .relay R2. TheV indicator lampe will function as before to .indicate to the despatcher when relay L2 becomes energized. When magnetl d has becomeenergized, the trainman will again-reverseswitch' W2 nection 'with switch W2, except that the trainman push button P2 will depress instead -of depressing -push button P1.' Y
1I 'have described for a few typical traflic move'- ments the operation oftheapparatus embodying my invention. From these descriptions and-'from v the'` accompanying drawing, the operation of the apparatus for every other possibletraiic movement .will be readily vunderstoodfwithout furtherl explanation. 1
Apparatus embodying, mylvinvention requires contemporaneousaction by the despatcher-andby a trainman to release a switchV for manual operation. 'The despatcher cannot therefore store the control of the switch without the cooperation of a trainrnan.` When a relayL has become' en'- ergized, it will remain energized only if'thed'oor -of thev corresponding one of the cases'containing levers V1 or A,V2 Vis left open. As longv as aA relay L remains energized, signal Sewill indicate stop vand indicator lamp e-will be extinguishedjhence lthe despatcher Vwill know at all times lwhether-the apparatus is in condition fork releasing the switch W1 or W2, and signal S will. give similar information to trainmen.
