对高效和可持续的城市内部交通系统的需求现已变得不可或缺。电动火车是通勤铁路服务的首选。然而，铁路全面电气化往往适用于交通密度足以证明固定成本高的使用率高的线路。目前，钛酸锂电池已被证明可以成功地为电动公交车提供动力，而电动公交车每乘客公里的能耗比火车高。本文以坦桑尼亚达累斯萨拉姆的一辆柴油通勤列车为例，研究了用电池供电的有轨电车取代短路线和空闲路线的柴油通勤列车，从而降低燃料成本和排放水平的可能性。有人指出，这种替代确实是可能的，也是有益的。与坦桑尼亚目前仅因燃油效率低而亏损的柴油通勤列车相比，电池动力电车的燃油成本和二氧化碳排放量分别降低了86.67%和64.96%。
The need for efficient and sustainable intracity transportation system has now become indispensable. Electric trains are highly preferred for commuter rail service. However, full railway electrification is often applied to heavily-used routes on which the density of traffic is sufficient to justify the high fixed costs. Currently, lithium titanate batteries have proven success powering electric buses which consume more energy per passenger kilometer than trains. In this paper, the possibility to replace diesel commuter trains serving short and idle routes with battery powered trams and hence reduce fuel cost and emission level was studied, siting a diesel commuter train in Dar es Salaam, Tanzania. It was observed that such a replacement is indeed possible and gainful. Compared to the diesel commuter train in Tanzania which current operates at loss merely due to low fuel efficiency, the battery powered tram was found to reduce fuel cost and carbon dioxide emission by 86.67% and 64.96% respectively.
