No the driving cab of a 156 is miles better than a 150 which is miles better than a 142. 142s are absolute bobbins when it comes to the cab. The ONLY part of a 142 cab that is superior is the 2nd mans side, which is good news for instructors but not for drivers. Apart from that they are inferior in every way possible. The drivers side is uncomfortable and extremely cramped. You have to slide the seat backwards then forwards just to get in and out of the seat, thats what I call cramped. The cab side windows are bus windows.
It is all personal taste I guess. I despise 150/1's more than any other Northern Unit, my mate who drives them preferes them to any other train. Ha ha. There is no right or wrong, only opinion. My friend prefers banking with Barclays, I have worked in finance for decades and think Barclays are the scum of the earth. Who am I to tell my mate he is wrong. Ha ha.
