563.3.2.2. WEIGHT LIMITSMaximum training weightAxle weight and metre run weightADIF lines are classified into ninecategories, whose defining characteristicsare outlined in the following table,according to the weight admitted peraxle or per metre run.The Maximum Weight Table is the officialdocument that lays down the trailingweights for each locomotive on thevarious Network lines.Maximum weight is generally determinedon the basis of two parameters:Axle run and metre run weightLINETYPEMAXIMUM MASSPer AXLEPer METREA 16.0 t 5.0 tB1 18.0 t 5.0 tB2 18.0 t 6.4 tC2 20.0 t 6.4 tC3 20.0 t 7.2 tC4 20.0 t 8.0 tD2 22.5 t 6.4 tD3 22.5 t 7.2 tD4 22.5 t 8.0 tMost lines on the ADIF ManagedNetwork are currently Class D4. Somespecific restrictions do however existwhich affect certain points and lines, andwhich can be consulted in the OperatingManual.• The most unfavourable line gradient onthe train route.• The maximum locomotive weight,according to the line gradient above.• The maximum weight representsthe weight a locomotive cantechnically pull in extreme operatingconditions.Application of the maximum weight to trains maygive rise, especially in diesel locomotives, to lowrunning speeds, which may be incompatiblewith the operation or a reasonable use of trackcapacity.This is why, regardless of the maximumweight established, ADIF may set conditionsor reject requests that lead to unsuitablespeeds due to the weight proposed by theCandidate.3.3.2.3. LINE GRADIENTSMap 5 in Annex G shows the line gradients onthe most important sections of the network inboth running directions.
