Hi Kentvette ,
I have never been on a road engine but can well imagine all the well oiled valve gear flailing about right in your face covering you in oil ! At least on a railway loco all the waggly oily bits are either on the outside or underneath or if a 3 or 4 cylinder loco , a case of both ! Nearly everything is manually lubricated and with so many corks in oil pots and bearings that if the loco fell in a river it would float
The Great Western Railway ` King ` class 4 cylinder locos had 148 oiling up points that the driver has go round with an oil can before each trip ! You felt like you had done half a days work before you even turned a wheel
My best mate and railway buddy of nearly 40 years was an Ashford guy who started out as a freight train guard and ended up as Diesel Traction Depot Manager at Coalville .
