Tags: bogies curves elevation freight consist physics prime mover track physics train physics. Joined: Aug 24, Messages: Likes Received: I bought a locomotive as an add-on DLC. It is one of many pushing and pulling a long US freight consist. We are decelerating by reducing throttle. We steadily descend from 35 mph towards At 30 i see the reason: a tight curve ahead.
My lead loco enters the curve at During our passage, i emerge, but the remaining long train traverses that loop of track, still at We remain Like a Jungfrau of old. Now a slight force can cause a large deflection, but this is a heavy freight train caught in a curve.
Only the track elevation and curvature deflect the curved path of what had been a train on a straight track. The bogies pivot for a good reason, but the axles are arranged about those pivot points, typically fore and aft. Imperfect, but relative to the track curvature and gauge, effectively aligned withe the curving track, but not centred on the track.
The curved track has an outer edge where an inner track surface carries wheel rim and flange. However, in the cab, it appears that this massive mechanical deflection exacts no visible cost in momentum. In my mind i hear the wheels screeching as the heavy long freight train rounds the tight curve. Why is this at no cost to the very heavy long train as might show on the speedometer?
Is the wheel noise NOT a reflection of increased friction along the curve? By Newton alone, deflection requires a force. This train is not a photon along a geodesic jet bundle traversing a gentle gravity well in space-time. Hence my doubts. Now about those Toronto screaming trams I choose Newtonian mechanics. And then there is physics in the 20th century: heat and black-body radiation. The turning wheels are deflecting, Kosten-frei.
