Abstract (en)
[origin: EP0640720A1] A vacuum machine for sucking up the ballast of a railway track has two ballast stores (17, 18) which each have their own sucking-in and discharge opening (35, 36) and to which is assigned a suction pipe (10) for sucking in the ballast. For selective airtight closure, in each case at least one sucking-in opening (35, 38) is assigned its own closure member (44, 45). Alternate emptying of the ballast stores (17, 18) can thus be carried out without interrupting the sucking-in activity. <IMAGE>
