From fddeea8b0e48e3bda81c3da5c90cb729eb8d3e31 Mon Sep 17 00:00:00 2001 From: pwarszawski Date: Sat, 7 Nov 2026 15:35:35 +0100 Subject: [PATCH] AI: use the locomotive releaser only when starting off The rule "wyluzuj lokomotywe, to szybciej ruszymy" released the locomotive's own brake whenever power was asked for and the locomotive cylinder held more than 0.4 bar. It had no speed condition, so it also fired in motion, at 50-75 km/h, right after an application. On a locomotive with the EStED distributor (E186) this vented the control reservoir; with the pipe not yet recharged the locomotive brake then faded to nothing at the next application. The rule is meant for starting off, so it now applies only below 1 km/h. --- vehicle/Driver.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/vehicle/Driver.cpp b/vehicle/Driver.cpp index 08f0c0d24..97ec36470 100644 --- a/vehicle/Driver.cpp +++ b/vehicle/Driver.cpp @@ -8057,8 +8057,11 @@ void TController::control_releaser() { } } // wyluzuj lokomotywę, to szybciej ruszymy + // this rule is for starting off, so only below 1 km/h: at speed, just after an application, it would vent + // the control reservoir of a locomotive that may have to brake again before the pipe has refilled it if( mvOccupied->BrakePress > 0.4 - && mvOccupied->Hamulec->GetCRP() > 4.9 ) { + && mvOccupied->Hamulec->GetCRP() > 4.9 + && mvOccupied->Vel < 1.0 ) { actuate = true; } // keep engine brakes released during coupling/uncoupling
