2100 pounds per hour. Here's how to figure: 35 pounds | 60 minute ----------------------------- = (35 x 60) pound/hour. = 2100 pounds per hour. 1 minute | 1 hour See that 60 minutes equals 1 hour, so dimensionally it has no effect on the quantity, but the minutes units cancel.
One ton per hour equals 33.3 pounds per minute.

hp Boiler = (4675 pound of water in an hour / 34.5 ) = (4675 pounds in an hour of steam at 212 oF / 34.5)
Boiler loads, or the capacity of steam boilers, are often rated in boiler horsepower, lbs of steam delivered per hour, or BTU. Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions. Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour.

That is a question that does not have one single answer. For instance, if the pressure of the steam is raised, less steam is needed. As pressure rises, temperature will also rise due to adiabatic work done on the steam. Also, higher temperatures are needed at higher pressures to make sure the steam does not condense. Raising the temperature of the steam at a given pressure also means that less steam is needed to provide the same amount of energy. Efficiency will also vary, depending on the turbine, and other factors, such ascondenser vacuum. In general, running a pressure around 40 - 45 PSI, it will take 20,000 - 25,000 pounds of steam per hour to generate one megawatt of electricity during that hour. This is with steam that is just above saturation (around 285°F). So, for 5 MW, you'd need around 100,000 pounds of steam an hour. The pipe size would depend on the turbine. A 55 MW turbine (common for geothermal), might have two pipes bringing steam in (one per side), both of which are around 30" in diameter. For 100,000 pounds of steam an hour, much smaller pipes would suffice. However, expanding and then compressing the steam repeatedly is something you want to avoid. Note that these figures reflect more of a geothermal application. The pressure and temperature of steam from a boiler will typically be much higher.

the steam train can go up to 90 - 110km per hour
There is no nice and easy formula to calculate what is being asked. Turbines and generators will have different efficiency curves. Nothing was mentioned about the pressure of the steam in the question. As the temperature and pressure of the steam rise, a pound of steam will contain more energy that can be used by the turbine. In general, though, 20,000 to 25,000 pounds of steam an hour flowing through a plant will give one megawatt of production. It is important to note this is for a power plant. The residential geothermal energy that is being used in houses is not a suitable energy source for power production.
