Locomotive vs Multiple Unit

What are the considerations needed to make between choosing a locomotive or MU to power a train?
I know passenger trains in Europe tend to be MU but freight is always locomotive hauled.

I'm not familiar with all locomotives around the world but in North America dynamic braking has been standard on locomotives built in the last 50 years, barring switchers

That's one of my main complaints with DMUs.
Travelling back home from Nottingham, the Voyagers were loud and rattled when stopped in a station. The HST was silky smooth in comparison with very little noise or vibration.

Though a Stadler FLIRT might be a good compromise. It's an EMU that can be converted to a DMU by adding a power pack that has all the diesel engines. That also allows for enough space to lower the floor and have level boarding in the UK.

Fair enough. Still, I'd expect it's easier to get the motors' tractive effort down to the rails via a dozen powering axles, compared to just four; ditto braking and recovering energy with a dozen axles with motor generators on them.

Atlanta here.
I've gotten in the habit of taking my shirt off before the ride and then going slow whenI near the destination, just fast enough to air-cool but without any real exertion. try to cool down as much as I can that way. then when I get off the bike I carry a washcloth and sponge down until I'm dry. then put on the shirt and join the destination.
I used to carry bandanas but I'd soak through those.

yeah, you get used to it and it becomes second nature.
I've got the opposite problem: I switched my fast bike to brifters and I'm still reaching down to nothing when I want to shift sometimes.

looks pretty neat. the big downside of old Peugeots is the obsolete french sizes but if it's running Shimano group then it's probably late enough model that uses regular stuff. hopefully . what's that steel decal say?

You have the saddle too far back and that tilt is ridiculous. Move it forward and up. A shorter stem and a seatpost without offset will help further.
Rigid is great if you get good tires and don't want to deal with expensive suspension. If good suspension isn't serviced regularly it dies. Cheap suspension is shit and very heavy.

This is treated more like a collectible, I feel kinda bad about it sometimes. Because I absolutely love it, I just rarely ride it. It’ll maybe see 20 miles in the summer.
