Train EB was applied in Auto mode with Obstructed Motion Detected showed on ATS. Released EB - ok. P roceeded in Auto mode to next station. ~~~~~ To further rectify.  3519 & #3520 AMR-2 contact resistance from 7046 to 7048 having higher fluctuating resistance when energised. OPS 30 raised to follow-up.  Sarma 44224 3520 Train EB was applied in Auto mode with Obstructed Motion Detected showed on ATS. Released EB - ok. Proceeded in Auto mode to next station.  519/520 ER D/L at 1610 hrs, found brake release command present but propulsion command not available. Requested LOC Log from SIG. Checked propulsion line breakers for abnormalities. Found #1520 & #2520 charging resistor(1 each) O/L. OPS 20 raised to follow-up.  Haiqal 44223 To further rectify.  3519 & #3520 AMR-2 relays replaced. Resistance when energised at 1.7 ohm. Further replaced the charging resistors at #1520 & # 2520 as reported earlier. Function check - OK. OPS 40 raised for M/L test.  Sarma 44225 Mainline Test.  519/520 M/L test from UPD-JKN-UPD. No fault was detected on both DT cabs.  Anand 44226
