But the amps stayed relatively the same over the points (about 235-245). If it slipped, they'd go down significantly for a moment. And maybe the HUD would indicate that as well. It probably is something else. On SPG I have to admit I could rely pretty fairly on Dash-8 dynamic, especially on the U-877 services, where there's 4 of them. Amps were pretty consistent and 4 locos could nicely hold the whole loaded coal train on the way down.
