Your missing out mate they have an almost alive feel to them , my uncle drove them late 50s early 60s got me addicted then ,nearly seventy now and still love the sound and smell of steam ,smoke and hot oil Rail or traction engines got something diesel can’t match,as for electric it’s got the character of a washing machine on wheels.
