How many T2 vagons per 1MW of train power do you think is optimal? Let's consider network on mainly flat map with occasional elevetions to avoid busy intersections. Maybe something like this:
- core fleet of 8 T2 vagons with 1 electric T2 locomotive. This allows nicely to reuse stations for different products with variable product proportions (for example 1/4 of the station loading bays for limestone and 3/4 iron). It has a decent top speed of 107, and acceptable climb rate of 17km/h for 12 degrees for occasional elevations. Isn't this too low for power ratio?
- complementary fleet of 4 T2 vagons with 1 electric T1 car. This is for low volume products, like sand in copper foundry, where 8*T2 would be idle most of the time and would be a waste of space and population. Also adding lots of products into 8*T2 station would cause unloading of 1 product to block other products, the overall throughput reduces significantly as the number of different exchanged products in a station increases.
It looks like adding more than 1 car for longer trains is inefficient because of more needed space for the stations thus more complicated layouts and 2 subsequent locomotives have less pushing power that 2 separate locomotives in total. Any train with more than 1 locomotive is better if split into several smaller trains by efficiency and space.
Are there any train patterns in general, that make train network more efficient?
